The eighth grade at Memorial Middle School is selling wrapping paper and gift bags to raise money for a field trip.
They sold one-half as many rolls of wrapping paper as they did gift bags. The profit they make for each roll of wrapping paper
is $2.50 and for each gift bag is $1.50. If the total profit was $704, how many gift bags were sold?
Answer: 256 gift bags (How?)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Let x be the number of gift bags sold.

Then the number of rolls of wrapping paper sold is x%2F2.

The value equation for the profit is 

%28x%2F2%29%2A2.50+%2B+x%2A1.50 = 704,

2.5x + 3x = 1408,

5.5x = 1408,

x = 1408%2F5.5 = 256.

Thus we found the number of gift bags sold. It is 256.
