The school band is having a car wash to raise money. Their goal is to collect $150. So far they have earned $10 each from three families and $5 each from fifteen families. How much more money do they have to earn to reach their goal?
They need $45 more to reach their goal of $150 because the $5 from the 15 families is $75 and $10 from the 3 families is $30 so together is $105, meaning 45 is needed.
