A candy store charges $12 per pound for truffles and $8 per pound for caramels. How much of each kind of candy should they put in a 3-pound gift box that will cost $29?

1.25 pounds truffles + 1.75 pounds caramels

Step-by-step explanation:

12x + 8 (3-x) = 29

12x + 24 - 8x = 29

4x = 5

x = 5/4

1.25 X 12 = $15.00

1.75 X 8 = $ 14.00

$15.00 + $14.00 = $29.00
