Q:

Grace and her brother Sid want to raise money to go to band camp. Their parents have agreed to help them earn up to $400 by paying them $25 when one of them mows the lawn and $10 for each hour that one of them babysits their younger brother. They will have to do a combination of both chores in order to earn the money. Select the equation that represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.

Accepted Solution

A:
Answer:25m + 10b = 400Step-by-step explanation:Total amount that can be earned = $ 400Amount earned on mowing a lawn = $ 25Amount earned per hour on babysitting = $10Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25mAmount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b  Using the values from above, we can set up the equation as:400 = 25m + 10bor25m + 10b = 400This equation represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.Hope this helps have a good day
