Leo sold candy bars for a fundraiser. He spent $25 on a box of candy bars and sold them for $2 each. If his profit (after earning back the $25) was $69, how many candy bars did Leo sell?
Which equation can be used to solve the problem?
1. $2c+$25=$692 dollars plus 25 dollars is equal to 69 dollars
2. $2c=$69−$252 dollars is equal to 69 dollars minus 25 dollars
3. $25−$2c=$6925 dollars minus 2 dollars is equal to 69 dollars
4. $2c−$25=$69
