Q. 9,900 dollars is placed in a savings account with an annual interest rate of 1.7%. If no money is added or removed from the account, which equation represents how much will be in the account after 8 years?M=9,900(0.017)8M=9,900(1.017)8M=9,900(1+0.017)(1+0.017)(1+0.017)(1+0.017)M=9,900(0.983)8
Use Compound Interest Formula: To find the total amount in the account after 8 years with compound interest, we use the formula for compound interest: A=P(1+r/n)(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.
Identify Given Values: In this problem, P=$9,900, r=1.7% or 0.017 as a decimal, n=1 (since the interest is compounded annually), and t=8 years. We need to plug these values into the compound interest formula.
Substitute Values: Substituting the given values into the compound interest formula, we get A=9,900(1+0.017/1)(1∗8).
Simplify Equation: Simplify the equation to get A=9,900(1+0.017)8.
Final Account Amount: Further simplifying, we get A=9,900(1.017)8. This is the correct equation that represents how much will be in the account after 8 years.
