Question

Coach purchased footballs and basketballs from two different stores.

Answer 1

Answer:

• $6.25

Step-by-step explanation:

Let football cost be f and basketball cost be b

We have two equations as per given:

• 5f + 14b = 110
• 10f + 6b = 82.50

We need to find b, therefore we'll eliminate f

To do so we'll double the first equation and subtract the second one:

• 2(5f + 14b) - (10f + 6b) = 2(110) - 82.50
• 28b - 6b = 220 - 82.50
• 22b = 137.5
• b = 137.5/22
• b = 6.25

Each basketball costs $6.25
