Question

earl is ordering supplies. yellow paper costs $5.00 per ream while white paper costs $6.50 per ream. he would like to order 100 reams total, and has a budget of $536. how many reams of each color should he order? yellow paper reams white paper reams

Answer 1

White paper = 24 reams

Yellow paper = 76 reams

Explanation:

let w = white paper and y = yellow paper

5y + 6.5w = $536 Eq.1

y + w = 100 Eq.2

multiply eq.2 by -5 and add to eq.1 to eliminate the y

5y + 6.5w = 536

-5y - 5w = -500

______________

1.5w = 36

w = 24

Use any of the equations and substitute w = 24

y + w = 100

y + 24 = 100

y = 76
