Identify the deposit amount and the fee structure for a cash deposit at a branch counter on 17/12.

From Table 1, on 17/12, a cash deposit of R600,00 was made at the branch counter.
From Table 2, the fee for "Cash deposit: Branch counter" is R8,00 + R1,95 per R100.

The variable fee is R1,95 for every R100 deposited.
For a R600 deposit, there are $\frac{\text{R}600}{\text{R}100} = 6$ units of R100.
Variable fee portion $= 6 \times \text{R}1,95 = \text{R}11,70$.

Total deposit fee $= \text{Fixed fee} + \text{Variable fee portion}$
Total deposit fee $= \text{R}8,00 + \text{R}11,70 = \text{R}19,70$.

The deposit fee of R19,70 on 17/12 was calculated as:
