How do you solve part iv? I think I’ve been studying for too long, and my brain is all over the place — I’m so confused 😭. I’ve also included the answers for the first three parts.

i havent done it but just looking at it id assume u
1. calculate the total amount after the 5 months of contributions
2. make a new geometric series using the new contribution amount
3. solve for the An = 60000 to find at which time period he pays off the 60000. This number will be a decimal, you round down the decimal to find the amount of time periods he can make FULL contributions, and then plug that into the formula to find the amount
4. As the amount is compounded at the end of the month, after he makes a contribution, you must compound this amount one more time before he can make his final repayment
5. subtract this from his goal of 6000 and this is the total payment he has to make

(i think idk tho)
