Question

Mike and brad have 30 to spend making models cars. Since wheels cost 0.50 each they decide they will be able to make more cars if they use three wheels instead of four. The car body and other material cost 1.25 per car. How many cars will they be able to make

Answer 1

Total number of car make = 10 cars

Explanation:

Given:

Total amount = 30

Each wheel cost = 0.50

Other material cost 1.25 per car

Find:

How many cars make

Computation:

Cost of one car = 3(0.50) + 1.25

Cost of one car = 1.50 + 1.25

Cost of one car = 2.75

Assume, total number of car = a

So,

2.75(a) = 30

a = 10.9090

So,

Total number of car make = 10 cars
