At an effective annual interest rate of ii, i > 0, each of the following two sets of payments has present value K: i) A payment of 121 immediately and another payment of 121 at the end of one year.
ii) A payment of 144 at the end of two years and another payment of 144 at the end of three years.
Calculate K.
a) 1/7.
b) 1/8.
c. 1/9.
d. 1/10.
e. 1/11.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
