How many different ways can you make 60 cents with quatrers and nickels?

Answer 1

To make 60c, you can have no more than 2 quarters, because if you had 3 quarters that would make 75c, which is too much.

So, you could make 60c with no quarters and some nickels, 1 quarter and some nickels, or 2 quarters and some nickels.

If you have no quarters, you would need 12 nickels (12 x 5 = 60)

if you had 1 quarter, you would need 7 nickels (7 x 5 = 35, 35 + 25 = 60)

If you had 2 quarters, you would need 2 nickels (2 x 5 = 10, 25 x 2 = 50, 10 + 50 = 60)

So, if you have to make 60c using quarters AND nickels, there are two different ways to do it:

1 quarter + 7 nickels

2 quarters + 2 nickels
