Exercise 11 Page 157

Is the value of the new amount greater or less than the value of the original amount?

Increase; 30 %.

Practice makes perfect

To determine the percent change p, we can use the following general formula. p % =Amount of increase or decrease/Original amountFrom the given values, we can see the original amount was $5000 and the new amount is $6500. This is an increase in the amount. 6500-5000=$ 1500 The difference between the new amount and the original amount is $ 1500. Now we can use the formula.

Percent change=Amount of increase/Original amount
Percent change=1500/5000
Percent change=3/10
Percent change=0.3
Percent change = 30 %

The percent increase is 30 %.
