A student bought 4 coats at $98 each and a paid for them with only $20 bills. How many bills did it take?

Question

Math problem 

Answer 1

4 x 98 = $392

 

So you need to know how many $20 bills you need to have $392.

 

392 ÷ 20 = 19.6  twenty dollar bills.

Since you can't have .6 of a twenty dollar bill, he needed to have 20 twenty dollar bills.
