Rachel earns $150 per month from her job at the local library plus $6.00 per hour from babysitting jobs. If she wants to earn at least $300 this month, how many hours will she need to babysit?

Respuesta :

Americ
h= babysitting hours worked

Add her library and babysitting wages set equal to her goal of $300.

$150 + ($6 * h)= $300
150 + 6h= 300
subtract 150 from both sides
6h= 150
divide both sides by 6
h= 25 hours needed

CHECK:
$150 + ($6 * 25)= $300
150 + 150= $300
$300= $300

ANSWER: She needs to work 25 hours babysitting, in addition to her $150 library pay, to earn $300.

Hope this helps! :)
