Ms. Nina wants to buy candy mix for $1.00 per pound. If she already bought 50 pounds of candy for $1.20 per pound, how much candy that costs 80 cents per pound must she buy?

Answer 1

(50 * 1.2) + (x * .8) = 1 (50 + x)

60 + .8 x = 50 + x

Answer 2

Answer:

Ms. Nina Should buy 50 pounds of candy for $0.80 per pound.

How I found out:

(50 ∙ 1.2) + (x ∙ 0.8) = 50 + x
60 + 0.8x = 50 + x
60 - 50 = x - 0.8x
10 = 0.2x
x = 50
