A can of nuts sells for $4.50 and a box of microwaveable and a box of microwaveable popcorn sells for $3. You sell $252 in nuts and popcorn, and the boxes of popcorn sold is twice the amount of cans of nuts sold.How many boxes of popcorn did you sell?

Question

Equations:
n=can of nuts; p=microwaveable popcorn 

252=4.5n+3p
(2n=p)-3

   252=4.5n+3p
+ -6n=-3p
252-6n=4.5n
 +6n      +6n

(252=10.5n)/10.5
24=n

2(24)=p
48=p

252=4.5(24)+3(48)
252=108+144
252=252
