Exercise 2 Page 355

Recall that if a new amount is greater than the original amount, the percent change is called a percent increase. If the new amount is less than the original amount, the percent change is called a percent decrease. Consider the given amounts. Original Amount:&600 New Amount:& 660 We can see that the new amount is greater than the original amount, so the percent change is an increase. To determine the percent change p, we can use the following general formula. p % =Amount of increase or decrease/Original amount From the given values, we can see the original amount was 600 and the new amount is 660. This is an increase in the amount. Let's find the amount of increase. 660- 600= 60 The difference between the new amount and the original amount is 60. Now we can use the formula.

The percent increase of the second score over the first score is 10 %. This corresponds to answer G.
