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

`7(3)/(4)hr`

Step-by-step 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(1)/(2)+8(3)/(4)+6 \\ \Rightarrow32(1)/(4)hr \end{gathered}`

Now, we subtract this value from 40 hours:

`\begin{gathered} 40-32(1)/(4) \\ \Rightarrow7(3)/(4)hr \end{gathered}`

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