Susan started her business one month later and because of the price increase of products, it then cost
her R9,50 to make ONE cup of Milo. She calculated that the daily fixed cost was R90,00 and she would
be able to sell 100 cups of Milo per day. She will sell the Milo at R12,50 per cup.

Use the information above to answer the questions that follow:
1. Table 1 below shows the income from the side of cups of Milo

a) Determine the value of P in TABLE 2 above
b) Write down the equation that can be used to calculate the icome
c) Identify the independent variable in the table above.
2. Susan uses the following formula to determine the cost price of the cups of Milo.
Cost = R90,00 + R9,50 × n where n = number of cups of Milo
Table 2 below shows the cost price for a number of cups of Milo

Calculate the value o Q in the table 2 above.
3. The graph on the answer sheet below shows the total income for making up 100 cups of Milo.
Use the information in table 2 to draw another graph representing the cost from the selling of up
to 100 cups of Milo.
