Shota invests $2000 in a certificate of deposit that earns 2% in interest each year. Write a function that gives the total value V(t), in dollars, of the investment t years from now.
Q. Shota invests $2000 in a certificate of deposit that earns 2% in interest each year. Write a function that gives the total value V(t), in dollars, of the investment t years from now.
Identify Values and Formula: Identify the principal amount, interest rate, and the formula to calculate the total value of the investment after t years.Shota's principal investment (P) is $2000, and the annual interest rate (r) is 2%. The interest is compounded annually, so the formula to calculate the total value V(t) after t years is V(t)=P(1+r)t.
Convert Interest Rate: Convert the interest rate from a percentage to a decimal to use in the formula.The interest rate is 2%, which as a decimal is 0.02 (since 2%=1002=0.02).
Write Total Value Function: Write the function using the formula and the values identified in steps 1 and 2.The function that gives the total value V(t) of the investment after t years is:V(t)=2000(1+0.02)tThis function can be used to calculate the total value of the investment for any number of years t.
