Answer:
Interest rate = 0.9313
Explanation:
Future value or the cost of edcuation after 19 years = $184061
Present value, money in hand at present = $49327
Time period, n = 19
Future value = Present value (1 + r)²
184061 = 49327 (1 + r )²
(1 + r )² = 184061 ÷ 49327
(1 + r )² = 3.73
(1 + r) = √3.73
(1 + r) = 1.9313
r = 1.9313 - 1
r = 0.9313
Or Interest rate = 0.9313
