ANSWER:
15.75
STEP-BY-STEP EXPLANATION:
The week mentioned, is the first week, we add each day to where you volunteered, we must convert each number in its decimal form and then add, like this:
[tex]\begin{gathered} 3=3.0 \\ \\ 3.75=3.75 \\ \\ 4\frac{1}{4}=4.25 \\ \\ 4\frac{45}{60}=4.75 \\ \\ t=3+3.75+4.25+4.75 \\ \\ t=15.75\text{ hr} \end{gathered}[/tex]
Therefore, Julia’s total volunteer hours for the week of July 2 to 8 is 15.75
