To find the cost of 500 grams of apples, we first need to determine the cost per kilogram and then use that to find the cost for 500 grams.
-
Determine the cost per kilogram:
- A 5 kilogram bag of apples costs R65.
- The cost per kilogram is: \[ \text{Cost per kg} = \frac{\text{Total cost}}{\text{Weight in kg}} = \frac{65}{5} = R13 \text{ per kg} \]
-
Calculate the cost for 500 grams:
- Since 500 grams is half a kilogram (0.5 kg), we can calculate the cost: \[ \text{Cost for 500g} = \text{Cost per kg} \times 0.5 = R13 \times 0.5 = R6.50 \]
Therefore, the cost of 500 grams of apples is R6.50.
