Answer:

Step-by-step explanation:

Speed V = 6 1/2 = 13/2 miles/hr

Distance d = 7 3/4 = 31/4 miles

Time t = ?

V = d/t

Cross Multiply

Vt = d

t = d/v

t = 31/4 ÷ 13/2

t = 31/4 × 2/13

t = 31/(2×13)

t = 31/26

t = 1 5/26 hours

Ricky is taking out a personal loan for $12,000 to remodel his kitchen. He would like the lowest monthly payment possible, even
SSSSS [86.1K]

Let me help you, but first I will explain the formula used to calculate monthly compound interest.

The formula used to calculate compound monthly compound interest is

a=p(1+r/n)^nt

P Represents the principal

R Represents the rate (in decimal)

N is basically 12 months

T Represents the time (in years)

Let's plug the numbers in.

First statement

"His bank has offered him a loan at 13% interest for 36 months"

12000(1+.13/12)^(12)(3)

12000(1+.13/12)^(12)(3) = $17,686.64

Second statement

"12% interest for 60 months"

Plug in the numbers into the formula.

12000(1+.12/12)^(12)(5)

12000(1+.12/12)^(12)(5) = 21,000.36

<u>Answer</u>

The answer would be "13% interest for 36 months" as it is much lower compared to the other statement.
