Question 888021: One day a store sold 31 sweatshirts. White ones cost $11.95 and yellow ones cost $12.50. In all, $378.70 worth of sweatshirts were sold. How many of each color were sold? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! If all the sweatshirts sold were yellow, the store would have sold $387.50 worth of sweatshirts.
$387.50 - $378.70 = $8.80
The difference between the cost of the sweatshirts is $12.50 - $11.95, or .55
8.80 / .55 = 16
16 white sweatshirts were sold at a cost of $191.20, leaving
15 yellow sweatshirts sole (31-16) at a cost of $187.50
Total: $191.20 + $187.50 = $378.70
