quarters, dimes, nickels, pennies must be int

``````quarters= int(change/25);
dimes= int(change/10);
nickels= int(change/5);
pennies= int(change/1);``````

Also, your calculation isn't keeping track of the remainder after the higher coins have been returned. If you have 0.70 in change, your current calcs would show 2 quarters, 7 dimes, 14 nickels, etc. I think you want to display 2 quarters, 2 dimes as the result.
