You and your friend participate in a charity run. For every mile run, $2 is donated to the charity. You run 4 miles and your friend runs 3 miles. How much money, in dollars, do you and your friend raise for the charity?
Multiply each mile run by the amount of money for each mile. In this case, you run 4 miles and get $2 for each mile, so that's $8 for you. Your friend runs 3 miles, so that's another $6. Adding $8 plus $6 = $14.
