Steve invests 1,800 in an account that earns 3.7% annual interest, compounded continuously. What is the value of the account aft
Vlada [557]

Answer: the value of the account after 10 years is $2606

Step-by-step explanation:

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.

From the information given,

P = 1800

r = 3.7% = 3.7/100 = 0.037

t = 10 years

Therefore,

A = 1800 x 2.7183^(0.037 x 10)

A = 1800 x 2.7183^(0.37)

A = $2606 to the nearest dollar

insens350 [35]

Answer:

Total number of kilometers in the ride = 5 km

Number of kilometers Garret has already biked = k km

Number of kilometers Garret left to ride = 5 - k km

Number of minutes Garret takes per kilometer = 4 minutes.

Step-by-step explanation:

1. It takes 4 minutes for Garret to go a kilometer. Then

Number of minutes Garret takes per kilometer = 4 minutes.

2. Suppose the variable k is the number of kilometers Garret has already biked.

3. Garret is partway through a 20-minute bike ride. It takes 4 minutes for him to go a kilometer. Then

Total number of kilometers in the ride is

20\div 4=5\ km

4. Suppose the variable k is the number of kilometers Garret has already biked. Then 5-k km is the number of kilometers Garret left to ride.
