Maria is ordering copy paper for her office. The office is low on white paper and on blue paper. She will pay $3.50 per team of white paper and $3.75 per team of blue paper. If the purchase order is for $36.00 and she ordered 10 reams of paper, how many teams of white paper will she receive

Respuesta :

Kunchan
number of blue paper = b
number of white paper = w

3.5w + 3.75b = 36
w + b = 10

( w + b = 10 ) * 3.5
3.5w + 3.5b =35

3.5w + 3.75b = 36
3.5w + 3.5b =35

subtract the last equations
0.25b = 1
b = 4

w = 6

So the number of white reams she ordered 
6 reams
