Question

Gail bought 5 pounds of oranges and 2 pounds of bananas for $14. Her husband later bought 3 pounds of oranges and 6 pounds of bananas for $18. what was the cost per pound of the oranges and bananas

Answer 1

the cost per pound of the oranges = $2

the cost per pound of the bananas = $2

Explanation:

o=oranges

b=bananas

5o +2b = 14

3o + 6b =18

I will multiply the first by -3 to eliminate the b variable

-15o -6b = -42

3o +6b = 18

ADD BOTH

-12o = -24

o =2

5(2) +2b=14

10+2b=14

2b=4

b=2
