LaTanya buys 6 yards of blue fabric and 9 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $57. What would be the combined cost of 1 yard of blue fabric and yard of green fabric?

Respuesta :

answer:

$8

explanation:

blue fabric= x+2
green fabric= x

6(x+2) + 9(x) = 57

6x + 12 + 9x = 57

15x = 45

x = 3

blue fabric= (3) + 2 = 5
green fabric= 3

3 + 5 = $8
