Correct Answer: $3506.38

Step 1: Identify the principal amount (P), which is $2500.
Step 2: Identify the annual interest rate (r), which is 7%. Convert this to decimal form by dividing by 100: 7% = 0.07.
Step 3: Identify the number of years (n) the money is invested, which is 5 years.
Step 4: Use the compound interest formula: Amount = P(1 + r)^n.
Step 5: Substitute the values into the formula: Amount = 2500(1 + 0.07)^5.
Step 6: Calculate (1 + 0.07) = 1.07.
Step 7: Raise 1.07 to the power of 5: (1.07)^5 = 1.402552.
Step 8: Multiply the principal amount by this result: Amount = 2500 * 1.402552.
Step 9: Calculate the final amount: Amount = $3506.38.
