The question is this: you can afford monthly deposits of $200 into an account that pays 5.7% compounded monthly. how long will it be until you have $7,000 to buy a boat?
I used the formula FV=PMT([(1+i)^n-1]/i) but couldnt figure out how to solve for n. Please help me
first month 200x.057=11.40 (interest) ……….211.40 (balance)
second month 211.40x.057=12.05+200 …….. 423.45
third month 423.45x.057=24.14+200…………. 647.59
fourth month 647.59x.057=36.91=200 ………… 884.50
can you see how it goes? keep going like this and you will reach $7000
I am sure there is a shorter way to find your answer, but you can at least see how this works.
