A credit card company charges a late fee of 25 dollars each time a customer fails to pay on time. A customer missed the payment 4 times last year.

At the customer's request and out of courtesy, the credit card company decides to cancel all late fees for that year. Write a numerical expression to show how much money was return. Notice how the number 4 became negative. This is necessary so the amount of money the customer gets back is a positive number.

Adding integers word problems Here are four great examples about adding integers word problems.When the integers 10, 0, 5, -5,-7 are arranged in descending or ascending order, then find out which of the following integers always remains in the middle of the arrangement.

As we know, if a point or number lies on the right side to the other number, then the number is greater. Question 2: By observing the number line, state which of the following statements is not true? Here, B is greater than but smaller than 0 and A is greater than 0 but smaller than Also, 6 is smaller than A. Which of the following statements is not true? On the number line, it is shown as So, as we can see — 9 lies on the right hand side of On the number line, it is placed as Now, as we can see, -5 lies between 0 and-4 and and -6 and 6. But it does not lie between 0 and Water level in a well was 20 m below ground level. During rainy season, rainwater collected in different water tanks was drained into the well and the water level rises 5 m above the previous level.

The wall of the well is lm 20cm high and a pulley afixed at a height of 80 cm. Raghu wants to draw water from the well. The minimum length of the rope, that he can use is. Which of the following is the multiplicative identity for an integer o?

Which of the following is different from the others? Which of the following shows the maximum rise in temperature? But, division of integers may or may not be an integer. So, odd one is option c. So, odd one is option d. Here, option ab and c are the negative integers, but option d is not the negative integer. Additive inverse is the negation of a number.

As we know, addition is commutative for integers, i. So, a will be the answer. Zero 0 is an additive identity for integers, i. Let x be the missing number. When multiplying a positive integer and a negative integer, we multiply them as whole numbers and put a negative sign before the product. If we multiply even numbers of negative integers, then the resulting integer is positive. If we multiply six negative integers and six positive integers, then the resulting integer is positive, because even numbers of negative integers, in multiplication becomes positive.

If we multiply 5 positive integers and one negative integer, then the resulting integer is negative. Additive inverse of an integer is the same integer value, with opposite sign. So, we get additive inverse of integer a, when we multiply it by — 1.Katherine is very interested in cryogenics the science of very low temperatures. With the help of her science teacher she is doing an experiment on the affect of low temperatures on bacteria.

What was the temperature difference in the two experiments? What is the integer that represents the balance owed on the credit card? A B C D If it is F in Rantoul and it is 75F in Honolulu, what is the temperature difference between the two cities? During the football game, Justin caught three passes. One was for a touchdown and went 52 yards. The other was for a first down and was for 17 yards. The other was on a screen pass that did not work so well and ended up a gain of yards. What was the total yardage gained by Justin on the pass plays?

James plays in the backfield of the Big Town football team. Last week he ran four plays from the halfback position. He made "gains" measured in yards of 3, 4, 1, and 5. What were his average yards per gain? Round your answer to the nearest tenth of a yard. In golf, the average score a good player should be able to achieve is called "par. Scores in golf are often expressed at some number either greater than or less than par.

A B C D 4.In another set of lessons, we have some examples of Integer Word Problems that involve two unknowns. Integer Problems with three unknowns are not necessarily more difficult than integer word problems with two unknowns. You just have to be careful when relating the different unknowns.

Example: Jane and her friends were selling cookies. They sold 4 more boxes the second week than they did the first.

On the third week, they doubled the sale of their second week. Altogether, they sold a total of boxes.

In these lessons, we will look at Integer Word Problems that have more than two unknowns.The markets likely assume the poll numbers coming out of the convention will continue to look good.

I think anything over 4 pp on Pollster will be an upswing in the markets and below 4 pp a downswing. Rolling into Philadelphia now. Will live blog and tweet as the night progresses. This time, not from the arena, but a well situated bar near the arena. Welcome to Night 4 of the RNC. I am live, in the arena, as the action unfolds.

Follow me either on PredictWise or Twitter. I am at the RNC. Not sure what I am going to see, but I am credentialed member of the press for the next two days.

In the meanwhile, will tweet out updates if anything changes. But, should not be a huge worry. UPDATE: all fixed by 11:30 AM ET today. Sorry for any issues Are prediction markets now too stable, because people trust them too much. I explore with Andrew Gelman in a new post at Slate. I know it is not as sexy or important as the president, but senate races are just really exciting. Wisconsin and Illinois are very likely Democrats gains from Republicans in blue states.

Nevada is now a tight hold for the Democrats. Indiana, Pennsylvania, New Hampshire, and Florid are all leaning Republican by a whisker. Ohio and North Carolina are leaning Republican a little more strongly.
