Answer :
Answer: 35%
Step-by-step explanation: To find the percent decrease, we use the following formula.
[tex]\frac{Amount-of-change}{original-number}[/tex]
The amount of change is the difference between the two numbers which in this case is 60 - 39 and the first number is 60.
[tex]\frac{60 - 39}{60}[/tex]
60 - 39 is 21 so we are left with 21/60.
60 divided into 21 .35 times. However, our problem is asking for the percent which means we can move the decimal point two places to the right to get 35.
Therefore, the percent decrease is 35%.
