Question

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. How many pounds of chocolate costing $13.20 per pound should be mixed with 10 pounds of trail mix costing $3.90 per pound to create a mixture worth $9.16 per pound

Answer 1

Answer:

13lbs

Step-by-step explanation:

x = number of pounds of chocolate/lbs

13.20(x) + 3.90(10) = 9.16(x + 10)

13.2x + 39 = 9.16x + 91.6 (x100)

1320x + 3900 = 916x + 9160

404x = 5260

x = 1315/101 = 13.0198.... ⇒ 13lbs
