Question

jill earns $24 per hour. how much does jill earn for 7 hours ? how many hours would jill need to work to earn 120?

Answer 1

Let x be the hours worked by Jill.

We'll have that the expression that represents Jill's earnings is:

`24x`

For 7 hours,

`24(7)=168`

Jill will make $168

If the earnings were 120,

`24x=120`

Solving for x :

`\begin{gathered} 24x=120 \\ \rightarrow x=(120)/(24) \\ \Rightarrow x=5 \end{gathered}`

Therefore, Jill would need to work 5 hours to earn
