Question

Maisie has saved up $50 to buy concert tickets, but the tickets cost $125. She is able to earn $15 per day by walking her neighbor’s dogs. How many days will Maisie have to walk the dogs to earn enough money to buy the tickets? Let d = the number of days worked.

Answer 1

125=15d+50
-50 -50
75=15d
5=d

Answer 2

$125-50=$75
So,15+15+15+15+15=$75
D=5
