Helen deposited $1200 at 5% interest compounded continuously. After 6 years, how much did she have?

(A) $1619.83
(B) $1560
(C) $2410.26
(D) $1608.11
(E) none of these

I got (D), but got it wrong. Would (A) be the correct answer?

A

Step-by-step explanation:

X = 1200 × e^(5% × t)

X = 1200 × e(0.05×6)

X = 1200 × e^0.3

X = 1619.830569

step-by-step explanation:

$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
