How many years will it take $2,000 to grow to $3,300 if it is invested at 4.75% compounded​ continuously?

10.54263764

Step-by-step explanation:

It will take about 10.5 years for the investment to reach $3,300.

Step-by-step explanation:

Continuous compound is given by:

Where P is the principal, e is Euler's number, r is the rate, and t is the time (in this case in years).

Since our principal is $2,000 at a rate of 4.75% or 0.0475, our equation is:

We want to find the number of years it will take for our investment to reach $3,300. So, substitute 3300 for A and solve for t:

Divide both sides by 2000:

We can take the natural log of both sides:

Therefore:

It will take about 10.5 years for the investment to reach $3,300.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
