Question

If three lates were £7 how much would 12 plates cost

Answer 1

To find the cost of 12 plates, divide the total cost of three plates (£7) by 3 to find the cost per plate, then multiply that cost by 12. The total for 12 plates would be £27.96.

Step-by-step explanation:

To calculate the cost of 12 plates based on the given information, we can set up a proportion because the cost per plate is constant. If three plates cost £7, we can determine the cost of one plate and then multiply that by 12 to find the total cost of 12 plates.

Step-by-Step Calculation:

1. First, find the cost of one plate by dividing the total cost by the number of plates: £7 ÷ 3 plates = £2.33 per plate (rounded to two decimal places).
2. Next, to find the cost for 12 plates, multiply the cost of one plate by 12: £2.33 per plate × 12 plates = £27.96.

Therefore, the cost for 12 plates would be £27.96.
