jelly beans math equation

Question

A store is having a sale on almonds and jelly beans. For 3 pounds of almonds and 2 pounds of jelly beans, the total cost is $11. for 8 pounds of almonds and 8 pounds of jelly beans, the total cost is $25 Find the cost for each pound of almonds and each pound of jelly beans.

Answer 1

THere is a misprint in the problem.

One of the numbers is incorrect.

3A + 2Jb = 11

8A + 8Jb = 25

elimination: -4 * eq1 + eq2

3A + 2Jb = 11

{(-4 * 3)+8}A = -44+25

-4A = -19

A=19/4 = $4.75

3*4.75 + 2*Jb = 11

2*Jb = -3.25

Jb = -1.625

Yes, it checks.
