Final answer:
To determine the interest earned in the first year on a $2,800 deposit at a 4% interest rate, multiply the principal by the interest rate. The calculation indicates that the interest earned in the first year is $112.
Step-by-step explanation:
The question asks how much interest will be earned in the first year on a $2,800 deposit in a savings account with a 4% interest rate. To calculate the simple interest for one year, you can use the formula: Interest = Principal × Rate × Time.
For this example, the Principal is $2,800, the Rate is 4% (or 0.04 as a decimal), and Time is 1 year. So the calculation would be as follows:
Interest = $2,800 × 0.04 × 1
After calculating this, you will find that the interest earned in the first year is $112.
