Answer:
x = 27 ; y = 35
Step-by-step 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
