Mike has $75 to spend at a local model car show. The entrance price for the show is $20. At one seller’s stand, Mike finds some model cars that he likes that are $7.50 each. What is the maximum number of model cars that Mike can buy at that stand?

Mike can buy 7 model cars

Step-by-step explanation:

The equation for this word problem would be

but since you cant buy a third of a car the answer would be 7

1.30
