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.

2 quarters & 2 nickels.
You can make 90 cents with three quarters and three nickels. (3 x 25) + (3 x 5) = 90 cents.

2 quarters & 2 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
You can make 90 cents with three quarters and three nickels. (3 x 25) + (3 x 5) = 90 cents.
fifty-five 1 quarter = 25 cents = 5 nickels = 5 x 5 cents 11 quarters = 275 cents = 55 nickels = 55 x 5 cents
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.
The minimum number of quarters, pennies, and nickels needed to make up 123 cents is 4 quarters, 4 nickels, and 3 pennies.
A US nickel is 5 cents, so convert the dimes and quarters to multiples of 5: One dime is 10 cents or 2 nickels, so 9 dimes would be equivalent to 18 nickels. A quarter is 25 cents or 5 nickels, so 6 quarters is 30 nickels.
Oh, dude, like, you can make 30 cents using nickels, dimes, and quarters in, like, 5 different ways. You can do it with 6 nickels, 3 dimes, or 1 quarter and 1 nickel, or 2 dimes and 2 nickels, or 1 dime and 4 nickels. So, yeah, there are, like, 5 ways to make that sweet 30 cents.
