Backlot Books sells used books. The store bought Henry's collection of old Farm and Home magazines for $195.00. They sold the lot for $427.50, and this gave them a profit of $1.50 per magazine. How many magazines did Henry sell them?
Solution
The profit was $427.50 - $195.00 = $232.50. Divide this by $1.50 to find the number of magazines: 155.
