Answer :
Answer: $560
A math tutor earns $128 for working 8 hours
The amount earned = $128
Working time = 8 hours
Using the rate formula
[tex]\begin{gathered} \text{Work = rate x time} \\ \text{Work = \$128} \\ \text{time = 8 hours} \\ 128\text{ = rate x 8} \\ \text{Divide both sides by 8} \\ \text{rate = }\frac{128}{8} \\ rate\text{ = \$16/ hour} \\ \text{This implies that the tutor received \$16/ hour} \\ \text{If he works for 35 hours} \\ \text{Total earned = 16 x 35} \\ \text{Total earned = \$560} \end{gathered}[/tex]The math tutor will earned a sum of $560 if he works for 35 hours
