Answer:
$7,986.25
Step-by-step explanation:
We can use the following formula to solve:
<em>P = principal value</em>
<em>r = rate (decimal)</em>
<em>t = time (years)</em>
<em />
First, change 15% into a decimal:
15% -> 
-> 0.15
Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:
Your car would be worth $7,986.25

Forming Equations from Word Problems</h2>
To form equations from word problems, we can derive mathematical operations as well as variables from the given information.
In this case, each time Walker reads a certain number of pages, we subtract that from the total number of pages left to know how many pages is left to read.
<h2>Solving the Question</h2>
<em>Let r represent the pages left to read.</em>
<em />
792 pages in total
Walker reads 15 pages a day during the week and 25 pages a day during the weekend.
- There are 5 weekdays, and he reads 15 pages each of those days. ⇒ <em>r</em> = 792 - 5×15
- There are 2 weekend days, and he reads 25 pages each of those days.
⇒ <em>r</em> = 792 - (5×15 + 2×25)
5 weeks have passed
- Multiply the terms representing the number of pages he reads a week by 5, for 5 weeks.
⇒ <em>r</em> = 792 - (5×15 + 2×25)×5
<h2>Answer</h2>
<em>r</em> = 792 - (5×15 + 2×25)×5
