You earn $72 for every 8 hours you spent shoveling snow. for every 3 hours you spend babysitting you spend 2 hours shoveling snow. you babysit for 15 hours in january. how much money do you earn in january?

$90

Step-by-step explanation:

Earning for 8 hours shoveling snow = $72

Amount per hour                                = $72/8 = $9

3 hours of babysitting                        =  2 hours shoveling snow

Babysitting hours in January             =  15 hours

Hours of shoveling snow in January = (15/3) x 2 = 10 hours

Amount earned in January                 = Hours shoveling snow x Hourly Rate

                                                             =    10 x $9 = $90

That is, you earn $90 in January.
