Grade 10 Term 3 Week 2-3 Lesson 2 Costing Grade 10 Term 3 Week 2-3 Lesson 2
Costing ingredients or materials Formula to calculate cost: Actual cost= Quantity used ×Purchase Price Quantity bought
Formula Actual cost: the cost of materials or ingredients used to produce the product/item
Quantity used: is the actual amount of ingredients/materials used
Purchase price: is the price paid for quantity bought
Quantity bought: is the amount of ingredients/materials bought
When purchasing products, e.g. eggs, you cannot buy 4 eggs only You will have to buy 6 or more and only use 4 as required by the recipe Therefore, you will only charge for the number of eggs used in the recipe You will use the formula discussed previously to calculate the actual cost
Example: According to the recipe, there are 4 eggs and 60 g of margarine. It is calculated as follows: Eggs: (from recipe) ↓ Actual cost = 4 × R16.99 → (purchasing price) (quantity bought) → 12 = R6.00
(Quickly do this calculation in the activity book) Margarine: 60 g used and 500 g bought at R16.99 Formula? Calculations? Actual cost?
When purchasing wool/sewing thread, you cannot purchase half the ball/reel You will have to buy full ball/reel Only half of the cost of the entire ball/reel needs to be included in the cost The other half will be used for another item/garment Then you will use the formula discussed previously to calculate the actual cost
Example: According to the pattern, ½ reel/ball needed for an item and quantity bought is 1 reel/ball at R11.00 Reel/ball: (from pattern) ↓ Actual cost = ½ × R11.00 → (purchasing price) (quantity bought) → 1 = R5.50
(Quickly do this calculation in the activity book) Buttons: Quantity needed and bought is 6. The price is: R2.00 for 12 buttons Formula? Calculations? Actual cost?
