    b. If you want to cover the printing costs by printing and selling only 50 copies of the book, at what price must you sell the book?

    Well we have to work out the cost of printing 50 copies of the book. Stick '50' into the function as X and work it out.

    Y = 1,550 + (4x) 4 x 50 = 200 1550 + 200 is 1750.

    Then we have to divide £1750 by 50 to work out how much we need to sell for to cover the cost.
