Let x - hours Carlos drove ; Let y - hours Maria drove
Equation 1: x + y = 4.4
x = 4.4 - y
Equation 2: 55x + 50y = 233
55(4.4 - y) + 50y = 233
242 - 55y + 50y = 233
-5y = 233-242
-5y = -9
y=9/5 or 1.8 hours Maria drove
To find time Carlos drove:
x=4.4 - 1.8
x = 2.6 hours
Since there was a down payment, the actual amount borrowed was
Amount borrowed, P=125000-25000=100000
interest, i = 4% (APR) = 0.04/12 per month (ASSUME compounded monthly)
Monthly payment = $577
To find the amortization portion of the first payment, we need the interest accumulated at the end of the first month (first payment)
= 100000*(0.04/12) = 333.33 (nearest cent)
Therefore amortization portion = $577-333.33 = 243.67 (to the nearest cent)
(by the way, if we need to know the amortization period, we have to use the amortization formula and estimate the number of months, n to give a monthly payment of 577 for the given principal. n can be calculated as 259.04 months, or over 21 years and 7 months).
You just have to multiply the numerators and the denominators.
The answer is 14 over 56. Then, you need to simplify the question.
So, since 56 is divisible by 14, divide the numerator and the denominator by 14.
Then you get your answer, which is one-fourth.
Hope that helped!
I think this is True. Because Perpendiculer Lines Rely On Right Angles. :)
