Chapter 7, Problem 24CT

To determine

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

Answer to Problem 24CT

The percent of change is a decrease of $15\%$ .

Explanation of Solution

Given Information: Original amount is $380$ and the new amount is $323$ .

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

The new amount $323$ is less than the original amount $380$ .

So, the amount of decrease is $380-323=57$ .

Therefore, percent of decrease (as a decimal) $=\frac{57}{380}=0.15$

To write the decimal $0.15$ as a percent, move the decimal point $2$ places to the right and suffix a $\%$ sign.

So, write $0.15$ as $15\%.$

Therefore, the percent change is a decrease of $15\%$ .
