If you did not reset your calculator after solving the previous TVM problem, like I suggested, then you only needed to change the interest rate and to solve for the number of periods (months) again. The answer is 44 months, as you can see here. With the interest rate significantly reduced, the number of periods (months) Cardi has to make payments is now 44, not 64 , a significant reduction. Way to go, Cardi, things are looking up! There's more good news though. Next, let's try to develop our TVM intuition some more. Without using a TVM calculator, try to answer the following question: if Cardi wanted to pay off the balance in half the time. Instead of paying $400 a month, how much would she need to pay per month, assuming all other factors being equal? This question is a bit tricky, and the answer may surprise you. Take your time to THINK before answer.[ng. a. More than $800 b. $200, half the $400 payment c. More than her current payment of $400, but less than $800 d. $800, double the $400 payment e. Less than $200 ment scenario: To pay the debt twice as fast as this, how much does she need to pay per month? The calculator will give you a negative number (payments to the credit card company is money out of her pocket), but please enter the answer as a positive amount. This way, Blackboard will auto-grade your answer correctly
