Brianna invested $25,000 in an account paying an interest rate of 5 1/8% compounded monthly. Wyatt invested $25,000 in an account paying an interest rate of 5 3/8% compounded continuously. After 16 years, how much more money would Wyatt have in his account than Brianna, to the nearest dollar?

Answer: The amount that Wyatt have in his account than Brianna is

$2420

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

Considering Brianna's investment,

P = 25000

r = 5.125% = 5.125/100 = 0.05125

n = 12 because it was compounded 12 times in a year.

t = 16 years

Therefore,.

A = 25000(1+0.05125/12)^12 × 16

A = 25000(1+0.00427)^192

A = 25000(1.00427)^192

A = 25000 × 2.2662

A = 56655

The formula for continuously compounded interest is

A = P x e (r x t)

Where

A represents the future value of the investment after t years.

P represents the present value or initial amount invested

r represents the interest rate

t represents the time in years for which the investment was made.

e is the mathematical constant approximated as 2.7183.

Considering Wyatt's investment,

P = 25000

r = 5.375% = 5.375/100 = 0.05375

t = 16 years

Therefore,.

A = 25000 x 2.7183^(0.05375 x 16)

A = 25000 x 2.7183^(0.86)

A = 25000 × 2.363

A = 59075

The amount that Wyatt have in his account than Brianna is

59075 - 56655 = $2420
