Answer:

Final answer is $\frac{80}{3}$ .

Step-by-step explanation:

We have been given an infinite geometric series.

Now we need to find it's sum.

common ratio $r=-\frac{1}{5}$ .

plug n=1 to get the first term

$a_n=32\left(-\frac{1}{5}\right)^{\left(n-1\right)}$

$a_1=32\left(-\frac{1}{5}\right)^{\left(1-1\right)}$

$a_1=32\left(-\frac{1}{5}\right)^{\left(0\right)}$

$a_1=32\left(1\right)$

$a_1=32$

Now plug these values into infinite sum formula

$S_{\infty}=\frac{a_1}{1-r}=\frac{32}{1-\left(-\frac{1}{5}\right)}=\frac{32}{1.2}=\frac{320}{12}=\frac{80}{3}$

Hence final answer is $\frac{80}{3}$ .

$\frac{1}{ {(3k)}^{ \frac{5}{2} } } = {(3k)}^{ - \frac{5}{2} } \\ = \frac{1}{( { \sqrt{3k}) }^{5} } = ({ \sqrt{3k} })^{ - 5}$

14% of $15,500 is $2,170. $15,500 minus $2,170 is $13,330.

When the car is on sale, the price is reduced from $15,500 to $13,330.
