QUESTION 4 Grаnt is а Grаde 11 learner with an entrepreneurial mindset. He stays clоse tо a recreatiоnal park and noticed that packs of fire wood and Styrofoam containers are in high demand on a regular basis. He processes the packs of wood at a cost of R9,00 and sells them at R15,00 per pack. The Styrofoam food containers are bought at R5,00 per pack and sold for R9,00 per pack. The table below shows the income from sales for five weeks. TABLE 3: The Income from sales of fire wood and containers for five weeks Product Week 1 Week 2 Week 3 Week 4 Week 5 Fire Wood R300 R270 R405 R300 R300 Containers R189 R126 R171 R135 R261 4.1 Determine the profit amount on ONE pack of fire wood. (2) 4.2 Determine the product with the highest percentage profit. You can use the following formula: Percentage profit = (Selling price – cost price) x 100 Cost price (7) 4.3 Which income from the sales of wood over the five weeks represents the mode? (2) 4.4 Determine the mean income for the styrofoam containers. (3) 4.5 The most popular product can be determined by comparing the number of units of product sold for a certain week. What was the most popular product sold in Week 5? Use calculations to justify your answer. (4) 4.6 Grant decides to increase the price of the wood from R15,00 to R20,00 per pack. Calculate the new percentage profit for one pack of wood. You can use the following formula: Percentage profit = (Selling price – cost price) x 100 Cost price Write your answer as a whole number. (4) 4.7 Determine the probability, as a percentage, of randomly selecting a week where the income for wood was more than R300. (3) Please do not type any answers in the box below. No typed answers will be accepted.
