Question 187174: a business invests $8,000 in a savings account for 2 years. at the beginning of teh second year, an additional $2500 is invested. At the end of the second year, the account balance is $ 11445. What was the annual interest rate?
So far I used the compounding interest formula where I = P(1 + r)^t
for the 1 st year's interest = (8000 + 8000r)
and for the second year's interest was (1st year's interest + [(8000+2500) + (8000r)(1 + r)^1] = total income after two years of 11445.
to set up my quadratic equation I combined like terms
8000 + 8000r + [(10500 + 8000r)(1 + r)] = 11445
8000 + 8000r + [10500 + 8000r + 10500r + 8000r^2] = 11445
combining terms 18500 + 26500r + 8000r^2 = 11445
or 8000r^2 + 26500r = 11445 - 18500 or -7055
8000r^2 + 26500r + 7055 = 0
at this point I get stuck because the numbers are too high in order to effectively use the quadratic formula to solve for r
I believe the answer is .05 or 5% annual interest rate..can you show me how you worked through the quadratic formula...
Thank you very much!
