Question

10. Sylvie needs $90.50 for a concert ticket. She already has $8 and she can earn the rest by working 7 hours at her job. Fill in the boxes to write an equation that can be solved to find h, Sylvie's hourly earnings.

Answer 1

We know that

• She needs $90.50 in total.

,

• She has $8.

,

• 7h is the amount she can earn at her job.

Having said that, we can define the following equation

$7h+8=90.50$

Then, we solve for h

$\begin{gathered} 7h=90.50-8 \\ h=\frac{82.5}{7} \\ h=11.79 \end{gathered}$

Sylvie's hourly earnings are $11.79.
