Michael has saved $40. He got a summer job mowing lawns, and gets $9 for every lawn he mows. How many lawns does Michael need to mow to save exactly $121, the cost of a concert ticket?

Answer :

Answer:

9

Step-by-step explanation:

9 × 9 = 81

81 + 40 = 121

121 is the amount of money you want so you just have to mow 9 lawns to get your exact amount of money you need.
