1 The term for the type of costs that changes as production level changes is variable costs.

Here are the solutions to your questions on short-run costs: 3.1 The term for the type of costs that changes as production level changes is variable costs. 3.2 Another term for inputs is factors of production. 3.3 The short run is an economic period during which at least one factor of production is fixed, while others are variable. This means a business cannot change all its inputs in the short run. 3.4 Step 1: Identify the variable costs from the table. Variable costs include raw material, water, and electricity. Step 2: Calculate the total variable costs (TVC). TVC = Raw material + Water + Electricity TVC = R3000 + R500 + R600 TVC = R4100 The total variable costs for Ms Sihle's business are R4100. 3.5 Step 1: Identify the fixed costs from the table. Fixed costs include rent and salaries. Step 2: Calculate the total fixed costs (TFC). TFC = Rent + Salaries TFC = R300 + R2000 TFC = R2300 The total fixed costs for Ms Sihle's business are R2300. 3.6 Step 1: State the formula for total costs (TC). TC = TFC + TVC Step 2: Substitute the calculated TFC and TVC values. TC = R2300 + R4100 TC = R6400 The total costs for Ms Sihle's business are R6400. 3.7 Step 1: State the formula for Average Fixed Cost (AFC). AFC = TFCQuantity (Q) Step 2: Substitute the TFC from 3.5 and the given quantity (100 units). AFC = R2300100 units AFC = R23 per unit The Average Fixed Cost for this business when producing 100 units is R23. That's 2 down. 3 left today — send the next one.
