In: Math
Assume that you have a balance of $5300 on your Discover credit
card and that you make no more charges. Assume that Discover
charges 21% APR and that each month you make only the minimum
payment of 2% of the balance.
Find how many months it will take to bring the remaining balance
down to $2500. (Round your answer to the nearest whole number.)
Answer is NOT 301
APR = 21% APR
so, Monthly it would be 21/1200 = 0.0175
Below is the table for APR - and from below table answer will be 301 only.
