1. ## 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 £p 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

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