    equation question

    Question: A market trader sells radios. She finds the number of radios she sell each week depends on the profit she makes per radio.
    she uses a formula to estimate the approximate number she will sell each week. It is

    N= 60-6p
    where N is the number of radios sold per week and úp is the profit per radio.
    (a) Write an expression, in terms of p, for the total profit per week from these radios.

    the answer in the books says p(60-6p)
    but can some please explain how thank you

    she makes $p$ profit per radio

    she sells $N=60-6p$ radios per week

    her weekly profit is

    $p_w = Np = (60-6p)p$
