Annual Percentage rate (APR) is calculated by the formula:
APR = 72i / {3P(n+1) + i(n-1)}
where:
i = Interest Rate
P = principal amount borrowed
n = number of months of the loan
Given:
Interest rate = $782.96
Principal amount = $4,000
number of months = 36 months
Substitute the given to the formula:
APR = 72(782.96) / [{3(4000)(36+1)} + {782.96(36-1)}]
APR = 56,373.12 / {444,000 + 27,403.60}
APR = 56,373.12 / 471,403.60
APR = .1196 X 100 ⇒ Multiply by 100 to get the percentage
APR = 11.96% or 12% (c)
I think the answer is 30 square units
Use the Pythagorean theorem:
The length of the hypotenuse is 6√2 units.
B.

Juan's time = x
Yumi's time = x + 2
Yumi's distance = 3 miles
Juan's distance = 2 miles
Rate = distance/time
Juan's rate = 2/x
Yumi's rate = 3/(x + 2)
The rates are equal so:
2/x = 3/(x + 2)
2x + 4 = 3x
x = 4 hours
Yumi's time = 4 + 2 = 6 hours
The answer is D.
