Answer:
Baseballs is: $10
Bats is: $4
Step-by-step explanation:
Let x represent bats
and y represent baseballs
So we have :
(1) 4x + 7y = 68
(2) x + y = 14 => y = 14 - x
Use substitution.
Substitute equation (2) into equation (1)
4x + 7(14 - x) = 68
Solve for x
4x + 98 -7x = 68
-3x + 98 = 68
-3x = -30
x = 10
Solve for y, replace x = 2 into equation (2)
y = 14 - 10 = 4, so y = 4
Since x represents bats and y represents baseballs, it cost $10 for the bats and $4 for the baseballs.
