Question

Rachael earned $42 for 3 1/2 hours at her job today. How much does Rachel earn per hour ?

Answer 1

$12

Explanation:

It is given that,

Rachael earned $42 for
`3(1)/(2)` hours at her job today. It means,

For 7/2 hours, earning is $42

For 1 hour, we divide $42 by 7/2 as follows :

`1\ h=(42)/((7)/(2))\\\\=(42* 2)/(7)\\\\=\$12`

So, he will earn $12 per hour.
