Q. Arianna deposits $450 every month into an account earning a monthly interest rate of 0.525%. How much would she have in the account after 24 months, to the nearest dollar? Use the following formula to determine your answer.A=d(i(1+i)n−1)A= the future value of the account after n periodsd= the amount invested at the end of each periodi= the interest rate per periodn= the number of periodsAnswer:
Identify Given Values: Identify the given values from the problem.Arianna deposits $450 every month, so d=$450.The monthly interest rate is 0.525%, so i=0.525/100=0.00525.The number of periods is 24 months, so n=24.
Convert Interest Rate: Convert the interest rate to a decimal.i=0.525%=1000.525=0.00525
Substitute Values: Substitute the values into the formula.A=d×(i(1+i)n−1)A=450×(0.00525(1+0.00525)24−1)
Calculate Future Value: Calculate the future value of the account after 24 periods.A=450∗(((1+0.00525)24−1)/0.00525)A=450∗(((1.00525)24−1)/0.00525)
Perform Exponentiation: Perform the exponentiation.(1.00525)24≈1.13269
Continue Calculation: Continue the calculation.A=450×((1.13269−1)/0.00525)A=450×(0.13269/0.00525)
Complete Division and Multiplication: Complete the division and multiplication.A=450×(25.274285714285715)A≈11373.428571428572
Round Final Answer: Round the final answer to the nearest dollar.A≈$11373
