Question

Christy earns money by working as a server at a restaurant and as a babysitter. Last week she made $82 at the restaurant and spent 8 hours babysitting. If she made a total of $154 last week, how much does she earn per hours of babysitting?

Answer 1

She makes $9/hour.

$82 (restaurant) - $154 (total) = $72 (babysitting)

$72 made babysitting / 8 hours spent babysitting

= $9/ hour
