error: invalid operands of types 'int' and 'double' to binary 'operator%'|

[ErinCorona]

I have tried all the fixes I found posted online, but they are not working for me. I've tried changing my data types, and I have included <cmath> but I still don't see how to fix this. Other advice has been to not use the pow function, but my teacher told us to use it.

Here is my program, this error is on line 50. Thank you in advance. (I'm sorry if this is not posted in the proper format, but I'm trying.) My error looks like this:
|50|error: invalid operands of types 'int' and 'double' to binary 'operator%'|

% works only on integer operands. Convert the right operand to an integer.

Thank you very much. I had tried that, but I did it wrong. Whew! Now I can work on all the calculation errors and finish my loop. Much appreciated. Great site.
