Hello, I have seem to be having trouble with my check funds function.
My code is not working properly when it reaches the penny if statement. For the result I get this [[“TWENTY”, 60.00], [“TEN”, 20.00], [“FIVE”, 15.00], [“ONE”, 1.00], [“QUARTER”, 0.50], [“DIME”, 0.20], ["PENNY", 0.03]]. Instead of the correct answer which is [[“TWENTY”, 60.00], [“TEN”, 20.00], [“FIVE”, 15.00], [“ONE”, 1.00], [“QUARTER”, 0.50], [“DIME”, 0.20], [“PENNY”, 0.04]].
I have been stuck on this for some time now. Any help will be appreciated.
