16 blue pens cost £2.40 and 18 red pens cost £2.70. Compare the cost of the pens and find out which is better value

Question

I'm not sure how to do this and even if I could I dont understand the question?

Answer 1

To compare the costs, you need to find the cost for each individual pen.

2.40/16 = £.15 for each blue pen

2.70/18 = £.15 for each red pen

They cost the same amount.
