d dimes
n nickels
s original STARTING amount of money in dollar units

Recheck this with the description and assigned variables. Does this make sense for you? If yes, then simplify and continue to solve. Notice only used d and n for dimes and nickels, and another variable for how many QUARTERS was not used; because reference was described for relating quarters to nickels as the same coin count.

------Notice that the equation using s was no longer needed.
