Given:
amount borrowed: 1,058
interest rate: 13%
term: 9 months
I'm assuming that the 13% rate is the annual interest rate. I'm also assuming that this problem is a simple interest problem.
Interest = Principal * rate * term
Interest = 1,058 * 13% * 9/12
Interest = 103.16
Total payment = Principal + interest
Total payment = 1,058 + 103.16 = 1,161.16
His monthly payment will be:
1,161.16 / 9 mos = 129.02
Devin will pay a 129.02 per month for 9 months to pay off his loan principal of 1,058 and the interest of 103.16.
Answer: X = 109, 109-20=89
Answer:
y = 6.5
Step-by-step explanation:
Using a ratio
10 13
----- = -----------
10+5 13+y
10 13
----- = -----------
15 13+y
Using cross products
10(13+y) = 13*15
10(13+y) = 195
130+10y = 195
Subtract 130 from each side
10y = 65
Divide by 10
y = 65/10
y = 6.5
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
