Sasha deposited \$1'250 into a money market account paying $2.50 \%$ interest for 2 years. Calculate the interest earned.

Step 1 ：Sasha deposited $1,250 into a money market account paying 2.50% interest for 2 years. We are asked to calculate the interest earned.

Step 2 ：The interest earned on a deposit can be calculated using the formula for simple interest, which is: \(\text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time}\)

Step 3 ：In this formula: - Principal is the initial amount of money deposited or loaned, which in this case is $1,250. - Rate is the annual interest rate, which in this case is 2.50% or 0.025 in decimal form. - Time is the length of time the money is deposited or loaned for, in years. In this case, it's 2 years.

Step 4 ：We can substitute these values into the formula to calculate the interest: \(\text{Interest} = 1250 \times 0.025 \times 2\)

Step 5 ：By calculating the above expression, we find that the interest earned is $62.5.

Step 6 ：Final Answer: The interest earned is \(\boxed{62.5}\)
