Can someone walk me through how I would enter this into the calculator TMV solver. Can it be done?

Jeremy has a balance owing of $4000 on his credit card. The credit-card company charges 18.0% annual interest, compounded monthly.

1.) If Jeremy makes payments of $300 every month, how much will he still owe after making 12 payments?

2.)Determine the monthly payment necessary to have the loan paid off in full after 12 payments.

i = .18/12 = .015

amount owing = 4000(1.015)^12 - 300[ 1.015^12 - 1]/.015
= .... you do the button - pushing

2. solve for 'paym'

4000 = paym [ 1 - 1.015^-12]/.015

paym = .... again, you do the button-pushing

Find an equation of the circle that satisfies the given conditions.

Endpoints of a diameter are
P(−2, 1) and Q(6, 7).

To solve these questions using a calculator, you need to use the Time Value of Money (TMV) formula. The TMV formula allows you to calculate the present value, future value, interest rate, or time period of an investment or loan.

The formula you will be using is:

PV = FV / (1 + r)^n

Where:
PV = Present Value (the amount owed after making payments)
FV = Future Value (the initial balance owed)
r = Interest rate per compounding period (monthly interest rate)
n = Number of compounding periods (number of payments)

1.) To calculate how much Jeremy will still owe after making 12 payments of $300 each, you need to find the future value (FV) when n = 12.

First, calculate the monthly interest rate (r). Since the annual interest rate is compounded monthly, you need to divide the annual interest rate by 12.

r = 18.0% / 12 = 1.5% (0.015 as a decimal)

Next, use the TMV formula:

FV = 4000 / (1 + 0.015)^12

Calculating this value will give you the amount Jeremy will still owe after making 12 payments.

2.) To determine the monthly payment necessary to have the loan paid off in full after 12 payments, you need to find the payment amount (PV) that will result in a future value (FV) of zero.

In this case, set the FV value to zero and solve for the payment (PV).

PV = 0.015 * 4000 / (1 - (1 + 0.015)^(-12))

Calculating this value will give you the monthly payment required to pay off the loan in full after 12 payments.

Now that we have explained the formulas and steps involved, you can use a financial calculator, spreadsheet software, or online calculators that have a built-in TMV function to input the formula and get quick answers.
