Question

Michelle wants to buy sporting goods. She has $3,495 to spend. Basketballs cost $75 each and footballs cost $42 each. What is the most of each kind of ball she can buy?

Answer 1

x = 27 ; y = 35

Explanation:

Amount to spend = 3495

Let : Number of basketball = x ; number of football = y

Cost per basketball = $75

Cost per football = $42

75x + 42y = 3495

We could insert reasonable values into x and y

Using the trial and compare option :

x = 27 ; y = 35

Compare :

75x + 42y = 3495

75(27) + 42(35) = 3495

2025 + 1470 = 3495
