Final answer:
The loan for the pottery factory's kiln will be paid off in approximately 11 years.
Step-by-step explanation:
The monthly payments for the pottery factory's kiln loan can be calculated using the formula PV = R(1-(1+i)^-n). In this case, the loan amount (PV) is $47,000, the monthly payment (R) is $480.84, and the annual interest rate (i) is 6.9%. To find the time (n) it takes to pay off the loan, we can rearrange the formula and solve for n. Plugging in the values, we get:
47,000 = 480.84(1-(1+0.069/12)^-n)
Dividing both sides by 480.84, we get:
97.805 = (1-(1+0.069/12)^-n)
Taking the natural logarithm of both sides, we can solve for n:
n ≈ 11 years
Therefore, the loan will be paid off in approximately 11 years.
