Exercise 61 Page 156

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

Increase; 32 %.

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 4.7 and the new amount is 6.2. This is an increase in the amount. 6.2-4.7= 1.5 The difference between the new amount and the original amount is 1.5. Now we can use the formula.

Percent change=Amount of increase/Original amount
Percent change=1.5/4.7
Percent change=0.319148...
Percent change≈ 0.32
Percent change ≈ 32 %

The percent increase is approximately 32 %.
