Final answer:
To calculate the value of Jack's investment after one year, we can use the formula for simple interest: Simple Interest = Principal x Rate x Time. Plugging in the values, we find that Jack's investment will be worth $5,340.72 after one year.
Step-by-step explanation:
To calculate the value of Jack's investment after one year, we can use the formula for simple interest:
Simple Interest = Principal x Rate x Time
In this case, the principal is $5,280, the rate is 1.15% (which can be written as 0.0115), and the time is one year. Plugging in these values, we get:
Simple Interest = $5,280 x 0.0115 x 1 = $60.72
To find out the total value of the investment after one year, we need to add the simple interest to the principal amount:
Total Value = Principal + Simple Interest = $5,280 + $60.72 = $5,340.72
Therefore, Jack's investment will be worth $5,340.72 after one year.
