A clothing business finds there is a linear relationship between the number of shirts, n (in thousands) it can sell and the price, P, it can charge per shirt. In particular, historical data shows that 3 thousand shirts can be sold at a price of $69 each, and that 7 thousand shirts can be sold at a price of $61 each. Find the equation of the form P(n)=mn+b that gives the price P they can charge for n thousand shirts.

Select the correct answer below:

P(n)=−4n+81

P(n)=−2n+75

P(n)=−2n+65

P(n)=2n+47

P(n)=−4n+89

P(n)=2n+63
