Question

from 74 hours to 85 hours find each percent change to the nearest percent if state if it's an increase or decrease​

Answer 1

Answer:

15% increase

Explanation:

we know that

74 hours represent the 100%

so

by proportion

Find out what percentage represent the difference between 85 hours and 74 hours (85-74=11 hours)

Let

x -----> the percent change

$\frac{74}{100\%}=\frac{11}{x}\\\\x=11(100\%)/74\\\\x=14.86\%$

Round to the nearest percent

$14.86\%=15\%$

Remember that

If the percent change is greater than 1, then the percent change is an increase

If the percent change is less than 1 and greater than 0, then the percent change is a decrease

In this problem the percent change is greater than 1

so

Is an increase
