Answer:
Step-by-step explanation:
Let x represent the amount that Andre's neighbor pay him each week to mow the lawn.
Andre always gives a $2 donation to the food bank in weeks when he earns money. Since it will take him 5 weeks to earn the money for his dad's gift, his total donation for 5 weeks will be 2×5 = $10
Andre wants to save $40 to buy a gift for his dad. It means that the amount that he gets paid for mowing the lawn - his total donations in 5 weeks = the amount that he wants to save. Therefore,
x - 10 = 40
x = 40 + 10 = $50
