A clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. In particular, historical data shows that 1,000shirts can be sold at a price of $30, while 3,000shirts can be sold at a price of $10. Find a linear equation in the form p(n)=mn+bthat gives the pricep they can charge for nshirts.

Because this answer involves an expression that is more complex than a whole number timesn, remember to type in multiplication symbols *. For example, if you wanted to enter12n, type this in as (1/2)*n.

p (n) =
