b. $71.10
c. $76.50
d. $85.50

Answer 1

To calculate the interest earned, we need to use the formula: Interest = Principal × Rate × Time. Given that Adriana invested $4,500 for 8 months at an interest rate of 1.9%, the interest earned is $57.37.

Step-by-step explanation:

To calculate the amount of interest earned, we need to use the formula:

Interest = Principal × Rate × Time

where:

• Principal is the amount of money invested
• Rate is the interest rate
• Time is the duration of the investment

Given that Adriana invested $4,500 for 8 months at an interest rate of 1.9%, we can calculate the interest earned by substituting the values into the formula:

Interest = $4,500 × 1.9% × (8/12)

Interest = $57.37 (rounded to the nearest cent)

The correct answer is not among the options provided. The closest option is $76.50, but this is incorrect. Therefore, the correct answer is not listed.
