What is the total cost for 1 man
Then for 12 people?
253 / 11 =23
23*12= 276

Can't help but think it's a trick question
yeah i figured it out that far is the price £27.60??:confused:

This forum is for you to get guidance, not answers.
What have you tried? (I assume it's 2k+k=2k22k+k = 2k^2…)
The cost for is the same for everyone despite the number so 12 people will also cost £253 (if this is suppose to be a trick question)

2k+k2k22k + k \neq 2k^2 (unless this is a question about solving a quadratic equation).

2k+k=3k2k + k = 3k

If so take two of something and add one more. You now have three of them.
