You can put this solution on YOUR website!
price of 1 small bag = x
price of 1 large bag = price of 1 small bag + $0.90 = x + 0.90
(5 large bags) + (3 small bags) = 17.22
5(x + 0.90) + 3x = 17.22
5x + 4.50 + 3x = 17.22
8x + 4.50 = 17.22
8x + 4.50 - 4.50 = 17.22 - 4.50
8x = 12.72
x = 1.59
small bag = $1.59
