The table represents the balance of Sylvia's loan, [tex] y [/tex], over a period of 24 months, [tex] x [/tex]. She used technology to create the scatter plot shown and determined the best-fit equation to model the data:

[tex] y = -382.05x + 25,077.40 [/tex]

Determine how long it will take to reach the given balances.

- month 60

Answer :

Sure! Let's determine how long it will take for Sylvia's loan balance to reach around [tex]$17,000 and $[/tex]0 using the best-fit equation provided. The equation modeling the data is:

[tex]\[ y = -382.05x + 25,077.40 \][/tex]

Step-by-Step Solution:

1. Find the time to reach a balance of [tex]$17,000:

- Set the equation for \( y \) equal to $[/tex]17,000:
[tex]\[
17,000 = -382.05x + 25,077.40
\][/tex]

- Solve for [tex]\( x \)[/tex]:
[tex]\[
382.05x = 25,077.40 - 17,000
\][/tex]
[tex]\[
382.05x = 8,077.40
\][/tex]
[tex]\[
x = \frac{8,077.40}{382.05} \approx 22.97
\][/tex]

This calculation shows that it will take approximately 23 months for the loan balance to be around [tex]$17,000.

2. Find the time to reach a balance of $[/tex]0:

- Set the equation for [tex]\( y \)[/tex] equal to [tex]$0:
\[
0 = -382.05x + 25,077.40
\]

- Solve for \( x \):
\[
382.05x = 25,077.40
\]
\[
x = \frac{25,077.40}{382.05} \approx 67.47
\]

This calculation shows that it will take approximately 67 months for the loan balance to reach $[/tex]0.

Answer:

- The balance of the loan will be approximately [tex]$17,000 at around month 23.
- The balance of the loan will reach $[/tex]0 at around month 67.
