Answer:
x = 7
Step-by-step explanation:
The angles are alternate interior angles, so for the lines to be parallel, the angle measures must be equal.
7x - 7 = 4x + 14
3x = 21
x = 7
Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>
The amount of money after t years in simple interest is modeled by:
In which:
- r is the interest rate, as a decimal.
The interest earned is:
A bank loaned out $14000, in two parts, hence:
Part of it at the rate of 9% per year and the rest at 17% per year, hence:
The interest received in one year totaled $2000, hence:
Then:
Isolating as a function of , then we can replace on the equation for the first interest.
Then:
$13,872 was loaned at 9%.
