salantis [7]

Answer:

$7,986.25

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value</em>

<em>r = rate (decimal)</em>

<em>t = time (years)</em>

<em />

First, change 15% into a decimal:

15% -> \frac{15}{100} -> 0.15

Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:

A=17,999(1-0.15)^5

A=7,986.25

Your car would be worth $7,986.25

Nostrana [21]
If Jana has to walk 2 blocks north to get to Kyle's home, then 3 blocks south to get to school, this means that she has just retraced the 2 blocks she walked to get to Kyle's home.

So the school is just 1 block south of Jana's home.
