What will be the cost of 27 tonnes of coal if 15 tonnes cost $360?

• A. 255
• B. 625
• C. 648
• D. 723

Answer: (C)

To determine the cost of 27 tonnes of coal when 15 tonnes cost $360, we first need to calculate the cost per tonne of coal. The cost per tonne can be found by dividing the total cost by the number of tonnes: Cost per tonne = Total cost / Number of tonnes Cost per tonne = $360 / 15 tonnes = $24 per tonne. Next, to find out the total cost for 27 tonnes, we multiply the cost per tonne by the number of tonnes we want to purchase: Total cost for 27 tonnes = Cost per tonne x Number of tonnes Total cost for 27 tonnes = $24/tonne x 27 tonnes = $648. Therefore, the total cost for 27 tonnes of coal is $648, which aligns with the correct answer provided.

To determine the cost of 27 tonnes of coal when 15 tonnes cost $360, we first need to calculate the cost per tonne of coal.

The cost per tonne can be found by dividing the total cost by the number of tonnes:

Cost per tonne = Total cost / Number of tonnes

Cost per tonne = $360 / 15 tonnes = $24 per tonne.

Next, to find out the total cost for 27 tonnes, we multiply the cost per tonne by the number of tonnes we want to purchase:

Total cost for 27 tonnes = Cost per tonne x Number of tonnes

Total cost for 27 tonnes = $24/tonne x 27 tonnes = $648.

Therefore, the total cost for 27 tonnes of coal is $648, which aligns with the correct answer provided.
