Answer 1

1. You're not looking for partial coins so dont use decimals, cast things as ints
int numberOfDimes = (int)((dollarAmount % .25m) / .10m)

Answer 2

2. Your formula for calculating nickels and pennys is broken,
int numberOfNickels = (int)((dollarAmount % .35m) / .05m)
this doesnt really make sense if you think, test it with 10 cents which shouldn't have a remainder because it's exactly 1 dime, the formula would instead tell you 2 nickels.
Try to figure out the formula yourself if you need more help you can post here

Answer 3

Convert.ToInt32() rounds to the nearest int, hence the "rounding errors".
Try Math.Floor() it rounds down.

Answer 4

I made some changes, but with int I believe I'm getting a rounding error with certain numbers. How do I make it more accurate?
