Question

Mike earned 20 for each lawn mowed and chris earned 15 for each lawn mowed. The teacher also gave them 50 dollars extra to help with the trip. They both mowed 10 lawns each by the end of the month. They need 500 for their trip. Do they have enough money for their trip? Write two expressions to determine the total amount earned. Write what the variable represents in each expression. Show your work.

Answer 1

20 x 10 + 50 = m(ike)

15 x 10 + 50 = c(hris)

200 + 50 = 250

150 + 50 = 200

250 + 200 = 450

450 is 50 less than 500, so no. They do not have enough money for the trip.
