Answer:
To calculate the interest earned by Diane and Henry, we can use the formulas for compound interest and simple interest.
For Diane (compound interest):
Principal amount (P) = $20,000
Interest rate (R) = 3% = 0.03
Time (T) = 1 year (for the first year)
For the first year:
Interest earned by Diane = P * R = $20,000 * 0.03 = $600
For Henry (simple interest):
Principal amount (P) = $20,000
Interest rate (R) = 3% = 0.03
Time (T) = 1 year (for the first year)
For the first year:
Interest earned by Henry = P * R = $20,000 * 0.03 = $600
So, for the first year, both Diane and Henry earn the same amount of interest, which is $600.
For the second and third years, since both Diane and Henry have their deposits unchanged and the interest rates are the same, the interest earned will also be the same.
Therefore, for each of the first three years:
Interest earned by Diane = $600
Interest earned by Henry = $600
So, for each of the first three years, Diane and Henry earn the same amount of interest.
The answer is: They earn the same amount.
Step-by-step explanation:
To calculate the interest earned by Diane and Henry, we can use the formulas for compound interest and simple interest.
For Diane (compound interest):
Principal amount (P) = $20,000
Interest rate (R) = 3% = 0.03
Time (T) = 1 year (for the first year)
For the first year:
Interest earned by Diane = P * R = $20,000 * 0.03 = $600
For Henry (simple interest):
Principal amount (P) = $20,000
Interest rate (R) = 3% = 0.03
Time (T) = 1 year (for the first year)
For the first year:
Interest earned by Henry = P * R = $20,000 * 0.03 = $600
So, for the first year, both Diane and Henry earn the same amount of interest, which is $600.
For the second and third years, since both Diane and Henry have their deposits unchanged and the interest rates are the same, the interest earned will also be the same.
Therefore, for each of the first three years:
Interest earned by Diane = $600
Interest earned by Henry = $600
So, for each of the first three years, Diane and Henry earn the same amount of interest.
The answer is: They earn the same amount.
