x=7
The rate of interest is 75 % per year
<em><u>Solution:</u></em>
Given that, Jamerra received a $3,00 car loan
she plans on paying off the loan in 2 years
<em><u>Jamerra will have paid $450 in interest</u></em>
Therefore, we get
Principal = $ 300
Number of years = 2
Simple Interest = $ 450
Rate of interest = ?
<em><u>The simple interest is given by formula:</u></em>
Where,
"p" is the principal and "n" is the number of years and "r" is the rate of Interest
<em><u>Substituting the given values we get,</u></em>
Thus rate of interest is 75 % per year
Answer: x = -1
Step-by-step explanation:
1) x - 5 = 36 -7x -49
2) x - 5 = -13 -7x
3) x + 7x =- 13 +5
4) 8x =- 8
5) x = -1
