Question

A store is having a sale on jelly beans and almonds. For 2

 pounds of jelly beans and 3

 pounds of almonds, the total cost is $10

. For 6

pounds of jelly beans and 5

 pounds of almonds, the total cost is $24

. Find the cost for each pound of jelly beans and each pound of almonds. 

Answer 1

if J = number of pounds of jelly beans and A = the number of pounds of almonds, we have

2J + 3A = 10 or 6J + 9A = 30

6J + 5A = 24 and 6J + 5A = 24 Solving the 2 equations together, we have

A = 6/4 = 1.5 and J = 2.75
