13. The square footage and monthly rental of 10 similar two-bedroom apartments yield the linear regression equation [tex]y = 1.165x + 615.23[/tex], where [tex]x[/tex] represents the square footage of the apartment and [tex]y[/tex] represents the monthly rental price.

a. Use the equation to determine the monthly rent for an apartment that has 1,500 square feet.

b. Based on the recommendation that you should spend no more than [tex]28\%[/tex] of your monthly gross income on housing, can Jacob afford this rental if he makes [tex]\$8,000[/tex] each month? Explain.

Answer :

Sure, I'd be happy to help with this!

Part (a): Calculate the Monthly Rent

We are given a linear regression equation that relates the square footage [tex]\( x \)[/tex] of an apartment to the monthly rental price [tex]\( y \)[/tex]:

[tex]\[
y = 1.165x + 615.23
\][/tex]

To find the monthly rent for an apartment with 1,500 square feet, we substitute [tex]\( x = 1500 \)[/tex] into the equation:

[tex]\[
y = 1.165(1500) + 615.23
\][/tex]

When you do the computation, you'll get:

- [tex]\( 1.165 \times 1500 = 1747.5 \)[/tex]
- Adding the constant: [tex]\( 1747.5 + 615.23 = 2362.73 \)[/tex]

So, the monthly rent for a 1,500 square foot apartment is approximately \[tex]$2,362.73.

Part (b): Determine if Jacob Can Afford the Rent

Jacob makes $[/tex]8,000 per month, and we need to determine if he can afford this rent based on the recommendation that no more than 28% of his monthly gross income should go towards housing.

First, calculate 28% of Jacob's monthly income:

[tex]\[
\text{Max affordable rent} = 0.28 \times 8000 = 2240
\][/tex]

So Jacob should not spend more than \[tex]$2,240 on rent each month.

Since the calculated rent of \$[/tex]2,362.73 exceeds \$2,240, Jacob cannot afford the apartment, as the rent is more than 28% of his monthly income.

I hope this breakdown helps! If you have any more questions, feel free to ask.
