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
[tex]\frac{74}{100\%}=\frac{11}{x}\\\\x=11(100\%)/74\\\\x=14.86\%[/tex]
Round to the nearest percent
[tex]14.86\%=15\%[/tex]
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
