    Make an equation and find the two prices of the shoes

    Hello! I would like some help with this task.
    Two manufacturers make "elevator shoes" for disco dancing of different qualities and the higher quality shoes sells for 8£ more than the others. As a shoekeeper, if you bought the cheaper type you could get five more pairs for £240. What are the prices of the two shoe types?

    Thank you!

    Haven't you been asking similar questions already? Try to have an attempt yourself.

    Let the cheaper variety of shoe = x and the more expensive type be y.

    You know that x + 8 = y (the more expensive shoes ' y' cost 8 pounds more than the less expensive ' x') . What else do you know?

    Use this:
    if you bought the cheaper type (x) you could get five more pairs for £240

    This is my attempt, however the answer are incorrect.
    x+5x=240
    6x=240
    x=40
    Can you please help me?

    The wording is strange, granted. I think they mean that 5 pairs of 'x' cost 240 pounds. So 5x=240 Then x=48. Does that match their answer?

    Let "x" be the price of the cheaper type of shoe, in pounds. Then the more expensive pair is x+ 8 pounds
    The number of cheaper shoes you could buy for £240 is 240/x. The number of more expensive pairs is 240/(x+ 8). Saying that you could get 5 more of the cheaper shoes means that 240/(x+8)- 240/x= 5.

    Thank you HallsofIvy, I understand now. However I believe that the equation should be like this: 240/(x+8)-5 = 240/x
