Answer
Explanation:
Step1: Identify compound - interest formula
The compound - interest formula when compounded monthly is $A = P(1+\frac{r}{n})^{nt}$, where $P$ is the principal amount, $r$ is the annual interest rate (in decimal), $n$ is the number of times interest is compounded per year, and $t$ is the number of years. Here, $P=$6000$, $r = 0.06$, and $n = 12$.
Step2: Calculate the amount for $t = 1$ year
Substitute $t = 1$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times1}\ &=6000(1 + 0.005)^{12}\ &=6000\times(1.005)^{12}\ &\approx6000\times1.0616778\ &\approx$6370.07 \end{align*} ]
Step3: Calculate the amount for $t = 2$ years
Substitute $t = 2$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times2}\ &=6000(1.005)^{24}\ &\approx6000\times1.1271602\ &\approx$6762.96 \end{align*} ]
Step4: Calculate the amount for $t = 3$ years
Substitute $t = 3$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times3}\ &=6000(1.005)^{36}\ &\approx6000\times1.1966806\ &\approx$7180.08 \end{align*} ]
Step5: Calculate the amount for $t = 4$ years
Substitute $t = 4$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times4}\ &=6000(1.005)^{48}\ &\approx6000\times1.2704892\ &\approx$7622.93 \end{align*} ]
Step6: Calculate the amount for $t = 5$ years
Substitute $t = 5$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times5}\ &=6000(1.005)^{60}\ &\approx6000\times1.3488502\ &\approx$8093.10 \end{align*} ]
Step7: Calculate the amount for $t = 6$ years
Substitute $t = 6$ into the formula: [ \begin{align*} A&=6000\left(1+\frac{0.06}{12}\right)^{12\times6}\ &=6000(1.005)^{72}\ &\approx6000\times1.4320449\ &\approx$8592.27 \end{align*} ]
