Answer 1

Given: A table for Jane's savings and expenditures is given.

Required: To determine the money earned through waitressing (A) and the interest(B).

Step-by-step explanation: Jane's aim is to save R1800 per month. If she saved R1800 for the period of 12 months, then the total money earned through waitressing is-

`\begin{gathered} A=12*1800 \\ =\text{ R}21600 \end{gathered}`

Now, she had R2000 already in the account. The interest she received on this amount is 5.5%. Hence, the amount of interest is-

`\begin{gathered} B=(2000*5.5)/(100) \\ =\text{R}110 \end{gathered}`

Final Answer: A=R 21600

B=R 110
