Final answer:
To find the cost of 18 plant pots when 6 cost £11.40, you determine the price of one pot (£1.90) and then multiply that by 18, which results in a total cost of £34.20.
Step-by-step explanation:
The question involves calculating the cost of plant pots given a known price for a set quantity and then scaling that up to find the cost for a larger quantity. If 6 plant pots cost £11.40, we first find the cost of one plant pot by dividing £11.40 by 6. Once we have the price of a single plant pot, we can multiply that price by 18 to find the total cost for 18 plant pots.
Steps to calculate the cost:
1. Divide the total cost of 6 pots (£11.40) by the number of pots (6) to find the cost of one pot.
2. Multiply the cost of one pot by 18 to find the total cost of 18 pots.
Now, let's perform the calculations:
1. £11.40 ÷ 6 = £1.90 (The cost of one plant pot)
2. £1.90 × 18 = £34.20 (The total cost for 18 plant pots)
Therefore, it would cost £34.20 to buy 18 plant pots.
