Question

You buy the following materials for the new extension. Calculate the cost of the bricks and cement and then work out the total cost of all the materials. Item Quantity Cost per item Cost (£) tonne of sand 2 £75.00 per tonne 150.00 bag of cement 20 £6.70 per bag Cost A bricks 350 45p per brick Cost B Total Cost Cost C Cost A (cement) = £ Cost B (bricks) = £ Cost C (total cost of all materials) = £

Answer 1

Cost of sand = £150

Cost of bricks = £157.5

Cost of cement = £134

Total cost = £441.50

Explanation:

We are given that:

2 tonnes of sand is for £75.00 per tonne,

20 bags of cement are for £6.70 per bag,

350 bricks at 45p each,

So, 2 tonnes of sand at £75.00 per tonne = 2 * £75.00 = £150.00

20 bags of cement at £6.70 per bag = 20 * £6.70 = £134.00

350 bricks at 45p each = 350 * £0.45 = £157.50

Therefore, the total cost of all the materials = £150 + £134 + £157.5 = £441.50
