4. In a manufacturing process, when 1000 units are produced, Renufacturing costs (assume all are variable costs) are incurred, while the manus). overheads amount to R5 000 (assume all are fixed costs). a. Calculate the total cost of production and the unit cost of the product. b. Now calculate the total cost of production and the unit cost of the product, if the number of units produced increases to 2000 units.

\begin{tabular}{|l|}\hline Question 2 \\ A reason for the presence or absence of a \\ relationship between beak depth and wing \\ length in this population would be? \\ Large beaks are likely associated with larger \\ birds in general; therefore, beak depth and \\ wing length for the drought-surviving birds are \\ not related. \\ birge beaks are likely associated with smaller \\ wing length for the drought-surviving birds are \\ not related. \\ \( \begin{array}{l}\text { Large beaks are likely associated with larger } \\ \text { birds in general; therefore, beak depth and } \\ \text { wing length for the drought-surviving birds are } \\ \text { related. }\end{array} \) \\ \( \begin{array}{l}\text { small beaks are likely associated with larger } \\ \text { birds in general; therefore, beak depth and } \\ \text { wing length for the drought-surviving birds are } \\ \text { rolated }\end{array} \) \\ \hline\end{tabular}
