Exercise 20 Page 415

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

17 % decrease

Practice makes perfect
To determine 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 $600 and the new amount is $500. This is a decrease in the amount. 600-500= 100 The difference between the new amount and the original amount is $100. Now we can use the formula.
Percent change=Amount of increase/Original amount
Percent change=100/600
Percent change=1/6
Percent change=0.17
Percent change = 17 %
The percent decrease is 17 %.
