He is paid $5.15 per hour.
First we find total number of hours he worked.
So, we will add all the value
\(\text{Total hours}=8+4\dfrac{1}{2}+3\dfrac{3}{4}+7\dfrac{1}{2}+4\dfrac{3}{4}\)
First we change mixed fraction to fraction
\(\text{Total hours}=8+\dfrac{9}{2}+\dfrac{15}{4}+\dfrac{15}{2}+\dfrac{19}{4}\)
\(\text{Total hours}=28.5\text{ hours}\)
Fred worked total 28.5 hours. He is paid $5.15 per hour.
Total earn = Total number of hours x Rate per hour
