There are 18 ways to make change for 75 cents with only quarters, dimes and nickels.
There are 43 combinations of various quantities of quarters (0, 1 or 2), dimes (0 to 5), nickels (0 to 10) and pennies (2 to 52) that make 52 cents.
2 nickels = 5+5 = 10 cents 2 quarters= 25+25= 50 cents therefore 50+10=60 so 2 quarters and 2 nickels is 60 cents
Five different ways.
The easiest way is to convert everything to cents first. - Seven nickels = 35 cents - Two quarters = 50 cents - so 7 nickels to 2 quarters is the same as 35/50, or 0.7 as a decimal number.

2 quarters & 2 nickels.
Start with zero nickels, and see what the combinations are: There is only 1 combination, which is 3 dimes and 1 quarter.Next use only 1 nickel, then you have: 2 quarters & 1 nickel, or 5 dimes & 1 nickel, so that's 2 additional combinations.Keep going with only 3 nickels, etc, till you get to 11 nickels = 55 cents. Note that there is no way to do it with only 8 or 10 nickels.This is the groundwork for answering. The answer is not yet finished.
