We have been given that you invest $100,000 in an account earning 8% interest compounded annually. We are asked to find the time it will take the amount to reach $300,000.
We will use compound interest formula to solve our given problem.
, where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.






Let us take natural log on both sides of equation.

Using natural log property
, we will get:




Upon rounding to nearest tenth of year, we will get:

Therefore, it will take approximately 14.3 years until the account holds $300,000.
Answer:
Step-by-step explanation:
A function maps an x-value to a single y-value. The graph of the parabola on the left does that.
The table on the right maps -1 to both 10 and 20, so does not meet the definition of a function.
