A person places $5540 in an investment account earning an annual rate of 2.5%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 20 years.

Answers

Answer:

$9,133.92

Explanation:

V = P*e^(rt)

V = 5540 * e ^ (0.025*20)

V = 5540 * e^(0.5)

V = 5540 * 1.648721

V = 9,133.9158

approximately $9,133.92

Little Billy lay down in his racecar-shaped bed and tried to sleep. Suddenly, the shutters of his window began to rattle and the knob of his bedroom door started twitching. Billy sat up. The door flew open and the ghost of the house's previous owner floated in, his clothing in rags, his face covered in scars, his shoulders hunched from the many chains draped over his torso. "I must have vengeance!" the ghost declared. "Well, go have vengeance somewhere else tonight," said Billy, as he sighed. "I have school tomorrow." He plopped back down, covered up, and went to sleep.
