**Reiny**, Thursday, December 15, 2011 at 5:31pmi = .09/12 = .0075

n = 12(7) = 84

let the payment be P

50000 = P(1 - 1.0075^-84)/.0075

P = 804.45

balance after 1 year

= 50000(1.0075)^12 - 804.45(1.0075^12 - 1)/.0075

= 44628.62

do the same steps for the last part of your question.

**Reiny**, Thursday, December 15, 2011 at 5:55pmI used the formula

Amount of single lump sum of money

= Principal (1 + i)^n

the present value of an annuity

PV = P( 1 - (1+i)^-n)/i

and the amount of an annuity

amount = P( (1+i)^n - 1)/i

where P is the annuity payment, i is the interest rate of each period expressed as a decimal and n is the number of periods

I showed all the steps necessary, I am sure you can insert any intermediate arithmetic answers if you need them

**Kimberly**, Thursday, December 15, 2011 at 7:26pmBalance owed at end of year 6

= 50000(1.0075)^72 - 804.45(1.0075^72 - 1)/.0075 = $9,198.86

Total repayment+ $67,574.13 based on $50,000 at 9% for 7 years.

Is this correct? Thanks for your help

= 50000(1.0075)^72-804.45(1.0075^72 - 6)/.0075= 9198.86
