The amount Tobie invests in a bank, P = $25
The annual compound interest rate, i = 4%
a. The principal is amount invested in the bank, P = $25
The annual interest rate, i = 4%

Where;
A(t) = The amount in the account after <em>t</em> years
P = The principal amount
i = The annual compound interest rate

c. The values to place in the table are found as follows;
At t = 0,
= 25
At t = 10,
= 37
The given table is presented as follows;

Step-by-step explanation:
It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:
810/1.5 = 540 km/hour
Then, multiply both the hour and the distance by 2:
540 * 2 = 1080 km/2 hours.
