Answer:

y = 85

Step-by-step explanation:

We would replace 'x' with 8 and then solve for 'y'.

=================================

y = 2.5x + 65; x = 8\\\rule{150}{0.5}\\y = 2.5(8) + 65\\\\y = 20 + 65\\\\\boxed{y = 85}

=================================

Hope this helps you.

the first simple interest will be $1.73 more than the second one.

<h3>Which is the difference between the two interests?</h3>

The loan is of $575, and there are two options:

7 years at 4.5% or 8 years at 3.9%

Remember that the simple interest formula is:

SI = (P*R*T)/100

Where:

P = principal value.

R = rate (this is the percentage per year)

T = time, in years.

Then for the first option. the interest will be:

SI = ($575*4.5*7)/100 = $181.13

For the second option we will have the interest:

SI'  =( $575*3.9*8)/100 = $179.4

The difference is:

$181.13 - $179.4 = $1.73

This means that the first simple interest will be $1.73 more than the second one.
