Q. Shota invests $1000 in a certificate of deposit that earns interest. The investment's value is multiplied by 1.02 each year.Which expression gives the investment's value after 5 years?Choose 1 answer:(A) 1000+1.025(B) 1000+(1+1.02)5(C) 1000⋅1.025(D) 1000⋅(1+1.02)5
Understand the problem: Understand the problem.We need to find the value of an investment after 5 years, where the investment increases by a factor of 1.02 each year.
Identify the correct expression: Identify the correct expression.The investment is multiplied by 1.02 each year, so we need to use an expression that represents this annual multiplication over 5 years.
Evaluate the options: Evaluate the options.(A) 1000+1.025 suggests an addition, which is incorrect for yearly multiplication.(B) 1000+(1+1.02)5 suggests adding 1 to 1.02 before raising to the power of 5, which is not the correct interpretation of the problem.(C) 1000×1.025 correctly represents the initial investment multiplied by 1.02 raised to the power of 5, which is the number of years.(D) 1000×(1+1.02)5 incorrectly suggests adding 1 to 1.02 before multiplying, which is not how the interest is applied.
Choose the correct expression: Choose the correct expression.The correct expression is (C) 1000×1.025 because it accurately represents the initial investment being multiplied by 1.02 each year for 5 years.
