Question

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?

Answer 1

Mike can buy 7 model cars

Explanation:

The equation for this word problem would be

7.5x+20=75

subract 20 from both sides

7.5x=55

divide both sides by 7.5

x= 7.33 or 7 1/3 or 22/3

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