Question: Scott wants to buy a skateboard. To make money, Scott sold berry smoothies for $3 a cup and cakes for $2 each. He sold 40 cups of smoothies and 18 cakes. How much money did he make? Think carefully first, then make a decision:
He made $3 / cup × 40 cups = $120 from the smoothies. He also made $2 / cake × 18 cakes = $36 from the cakes. Scott made a total of $120 + $36 = $156. So the answer is 156.
