2. You invest R7 400 at \( 10,5 \% \) simple interest for 3 months. 2.1 Calculate the interest you will receive during this period. 2.2 Calculate how much money you will have in your account after this time period.

To calculate the interest earned using simple interest, you can use the formula: \[ \text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time} \] Here, the principal is R7,400, the rate is 10.5% (or 0.105 in decimal form), and the time is 3 months (which is \( \frac{3}{12} \) years or 0.25 years). So, \[ \text{Interest} = R7,400 \times 0.105 \times 0.25 = R97.88 \] For the total amount in your account after 3 months, add the interest to the principal: \[ \text{Total Amount} = \text{Principal} + \text{Interest} = R7,400 + R97.88 = R7,497.88 \] You will receive R97.88 in interest, and after 3 months, you will have R7,497.88 in your account.
