Question

Aretha worked 4 days last week. The numbers of hours she worked each day is shown below. How many hours was she short of her normal 40-hour week?

Answer 1

ANSWER

$7\frac{3}{4}hr$

EXPLANATION

We want to find how many hours short she was of her normal 40-hour week.

To do this, we have to first find the total sum of hours she worked that week. To do this, add the hours from the 4 days that she worked:

$\begin{gathered} 10+7\frac{1}{2}+8\frac{3}{4}+6 \\ \Rightarrow32\frac{1}{4}hr \end{gathered}$

Now, we subtract this value from 40 hours:

$\begin{gathered} 40-32\frac{1}{4} \\ \Rightarrow7\frac{3}{4}hr \end{gathered}$

Hence, she was 7³/₄ hours short of her normal 40-hour week.
