Q & A

What is the relationship between time and money as presented in the script?

The script suggests that time and money are connected through the concept of interest. By depositing money and allowing it to grow over time, the future value of the money increases due to earned interest.

What decision does Sheila make after receiving her bonus?

Sheila decides to deposit her bonus for a year to earn interest, which will allow her to afford the car she has been wanting.

What is the present value of money?

The present value of money is the amount of money deposited today, before any interest is earned.

What is the future value of money?

The future value of money is the amount of money in the future after it has earned interest.

How does Sheila calculate the future value of her money?

Sheila calculates the future value by adding the interest earned to her initial deposit after one year, using a formula that connects the present value to the future value through the interest rate.

What is the interest rate's role in connecting present and future value?

The interest rate is the factor that links the present value to the future value. It determines how much money grows over a period of time.

What happens to Timmy's money after one year, and why is it still not enough to buy the car?

After one year, Timmy's money grows to $11,000, but it is still not enough to buy the car. This is because the price of the car exceeds his current savings plus the interest earned in that time.

How can Timmy increase the future value of his money over time?

Timmy can leave his money deposited for more years. The future value of his money will continue to grow each year as interest compounds, increasing the total value.

How is the time period represented in the future value formula?

The time period, or the number of years the money is left to earn interest, is represented as an exponent in the future value formula. The longer the money is left in the account, the higher the future value.

Why does Timmy need to wait 26 years to afford the car?

Timmy needs to wait 26 years because the future value of his deposit will take that long to grow large enough to cover the car's cost, based on the interest rate and his initial deposit.
