Question

Madison and Jim paid $21.08 for 1 large pizza,2 salads With the same price,and 2 drinks With the same price. The pizza cost $11.70,wich was 3 times as
much as the cost of one salad.They also used a coupon for $2 off their purchase. What was the cost of one drink?

Answer 1

1p + 2s + 2d - 2 = 21.08
but p = 11.7
and s = 11.7/3= 3.90

11.7 + 2(3.9) + 2 d - 2 = 21.08

solve for d, the cost of a drink

Answer 2

$6.63
