Calculate the cost of tiling a classroom floor and explain the pricing terms.

Welcome back ~Botshelo — been a while! Let's pick up where you left off. Here are the answers for Activity 3 and Activity 4. Activity 3: Cost of tiles Given: Classroom floor area = 63 m^2 Tiles cost = R180 per m^2 Step 1: Calculate the total cost of the tiles. Total cost of tiles = Area × Cost per m^2 Total cost of tiles = 63 m^2 × R180/m^2 Total cost of tiles = R11\,340 The total cost of the tiles is R11\,340. Step 2: Explain what "R180 per m^2" means. "R180 per m^2" means that for every square meter of tiles purchased, the cost is R180. It represents the unit price of the tiles. Step 3: If tiles increase by R20 per m^2, calculate the new cost. New cost per m^2 = Original cost per m^2 + Increase New cost per m^2 = R180/m^2 + R20/m^2 = R200/m^2 New total cost = Area × New cost per m^2 New total cost = 63 m^2 × R200/m^2 New total cost = R12\,600 The new total cost of the tiles is R12\,600. Activity 4: Tiling with labour Given: Area = 63 m^2 Contractor charges: Tiles: R180 per m^2 Labour: R60 per m^2 Call-out fee: R850 Step 1: Calculate the cost of tiles. Cost of tiles = Area × Cost per m^2 Cost of tiles = 63 m^2 × R180/m^2 Cost of tiles = R11\,340 The cost of tiles is R11\,340. Step 2: Calculate the labour cost. Labour cost = Area × Labour cost per m^2 Labour cost = 63 m^2 × R60/m^2 Labour cost = R3\,780 The labour cost is R3\,780. Step 3: Calculate the total cost of the job. Total cost of job = Cost of tiles + Labour cost + Call-out fee Total cost of job = R11\,340 + R3\,780 + R850 Total cost of job = R15\,970 The total cost of the job is R15\,970. Step 4: Which cost depends on area and which does not? • The cost of tiles and the labour cost depend on the area because they are calculated per square meter. • The call-out fee does not depend on the area; it is a fixed charge regardless of the size of the job.
