Thank you.

You have 70p and 60p but then the cost is 4p. Do the first set of p's stand for people?

This is my try, however I can see that it is incorrect. Can you please help me?
4n=70p
(n+1)=60

Hi anna55,

cost per orange =70p/n
cost per apple = 60p/n
the difference is 4p
assume p = pence
write the equation and solve the quadratic
