tatuchka [14]

Answer:

A, D, E

Step-by-step explanation:

The ratio height : base is ...

... 2.5 : 1.6

... = 25 : 16

... = 1.5625 : 1

You can eliminate the bogus answers B and C because ...

... B: the numbers are too close together. The larger would need to be near 13 for the smaller one to be 9.

... C: the base is larger than the height, so the ratio is less than 1, not greater than 1.

First, determine the effective interests given both interest rates.

(1)   ieff = (1 + 0.068/12)^12 - 1 = 0.07016
(2)   ieff = (1 + 0.078/12)^12 - 1 = 0.08085

Calculating the interests will entail us to use the equation,
     I = P ((1 + i)^n - 1)

Substituting the known values,
  (1)    I = ($5125)((1 + 0.07016)^1/2 - 1)
          I = $176.737

   (2)    I = ($5125)(1 + 0.08085)^1/2 - 1)
            I = $203.15

a. Hence, the greater interest will be that of the second loan. 

b. The difference between the interests,
    d = $203.15 - $176.737
          $26.413
