Terminal 2 input: 255.6 31 55 3 12.3

Summary
Interest on a credit card's unpaid balance is calculated
using the average daily balance.
Suppose that netBalance is the balance shown in the
bill, payment is the payment made, d1 is the number
of days in the billing cycle, and d2 is the number of
days payment is made before billing cycle.
Then, the average daily balance is:
averageDailyBalance = (netBalance * d1 payme
If the interest rate per month is, say, 0.0152, then the
interest on the unpaid balance is:
interest averageDailyBalance * 0.0152
Instructions
Write a program that accepts as input netBalance,
d1, payment, d2, and interest rate per month (
interestRate).

Follow-up Question

Everything in my terminal before "Enter net balance: 0.00" showed up on its own when I ran the program. I changed the formula to averageDailyBalance = (netBalance * d1 - payment * d2)/d1; and something I still incorrect. I sent over what I have on each side if you could help look over this
