First, calculate the discount.
15% of 1250 is 187.5
Then, subtract 187.5 from 1250.
You get 1062.5
Next, to calculate the sales tax. I'm not 100% sure if you're supposed to do this before the discount or after, I'm just assuming after.
Anyway,
6.5% of 1062.5 is approxamately 69.06.
Add that to 1062.5 to get the final answer of $1131.56
Present value PV= FV(1/(1+r)^n)
PV = Present Value
FV = Future Value
r= rate
n= number of years
Just plug in the numbers and calculate.
