The student Government wants to make a profit of at least $3000 from a magazines sales. At least $3000 simply means the profit should be $3000 and above.

There profit is $1.25 per magazine(m) subscription sold.

Their expenses are as follows

advertisement in school = $100

advertisement in community = $150

let

m = number of magazine sold

profit = selling price - cost price

selling price


1.25* m=1.25m

Cost price


100+150=\text{\$}250

Therefore,


\begin{gathered} 1.25m-250\ge3000 \\ \text{divide through by 1.25} \\ (1.25m)/(1.25)-(250)/(1.25)\ge(3000)/(1.25) \\ m-200\ge2400 \end{gathered}
