Solution by Steps
step 1
We start with the equation for the sinking fund: P×(1(1+0.04)9)0.04=6000 P \times \frac{(1 - (1 + 0.04)^{-9})}{0.04} = 6000
step 2
Rearranging the equation to solve for P P : P=6000×0.04(1(1+0.04)9) P = 6000 \times \frac{0.04}{(1 - (1 + 0.04)^{-9})}
step 3
Calculating (1+0.04)9 (1 + 0.04)^{-9} : (1+0.04)90.6651 (1 + 0.04)^{-9} \approx 0.6651
step 4
Substituting back into the equation: P=6000×0.04(10.6651) P = 6000 \times \frac{0.04}{(1 - 0.6651)}
step 5
Simplifying further: P=6000×0.040.3349806.958 P = 6000 \times \frac{0.04}{0.3349} \approx 806.958
Answer
The amount of each payment into the sinking fund is approximately $806.96
Key Concept
