To determine

To Calculate: The percent of change as an increase or decrease.

Answer to Problem 43CR

The percent of change is a decrease of 62.5%.

Explanation of Solution

Given Information: Original amount is 96 and the new amount is $36$ .

Formula Used:$Percentofchange,p\%=\frac{Amountofincreaseordecrease}{OriginalAmount}$

The new amount $36$ is less than the original amount $96$ .

So, the amount of decrease is $96-36=60.$

Therefore, percent of decrease (as a decimal) $=\frac{60}{96}=0.625$

To write the decimal $0.625$ as a percent, move the decimal point $2$ places to the right and suffix a $\%$ sign.

So, write $0.625$ as $62.5\%.$

Therefore, the percent change is a decrease of $62.5\%$.
