Sagot :

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.
