Jason has $3,491.15 in credit card debt. The annual interest rate on the unpaid balance is 19.4% compounded monthly. If Jason wants to pay off his credit card debt in 2 years, what is his monthly payment, assuming he makes no additional purchases on this card?

To calculate Jason's monthly payment, we can use the present value formula for an ordinary annuity:

\[PV = Pmt \times \left(1 - \frac{1}{(1+r)^n}\right) \div r\]

Where:
- PV = present value of the debt ($3,491.15)
- Pmt = monthly payment we need to find
- r = monthly interest rate (19.4%/12 = 0.0194/12 = 0.0162)
- n = number of payments (2 years * 12 months = 24)

Substitute the values into the formula:

\[3491.15 = Pmt \times \left(1 - \frac{1}{(1+0.0162)^{24}}\right) \div 0.0162\]

\[3491.15 = Pmt \times \left(1 - \frac{1}{(1.0162)^{24}}\right) \div 0.0162\]

\[3491.15 = Pmt \times \left(1 - \frac{1}{1.42571260655}\right) \div 0.0162\]

\[3491.15 = Pmt \times \left(1 - 0.70016346691\right) \div 0.0162\]

\[3491.15 = Pmt \times 0.29983653309 \div 0.0162\]

\[3491.15 = Pmt \times 18.534375\]

\[Pmt = 3491.15 / 18.534375\]

\[Pmt ≈ 188.45\]

Therefore, Jason's monthly payment to pay off his credit card debt in 2 years would be approximately $188.45.
