Answer 1

Answer:  p = -0.004n + 8

Step-by-step explanation:

Consider the number of shirts & the price as an x,y - coordinate

4000 shirts at $32  -->  (4000, 32)

5000 shirts at $28  --> (5000, 28)

Use the slope formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{28-32}{5000-4000}\quad =\dfrac{-4}{1000}\quad =-0.004$

Next, use the Point-Slope formula (replace x with n & replace y with p):

$y-y_1=m(x-x_1)\implies p-p_1=m(n-n_1)\\\\\\p-28=-0.004(n-5000)\\\\p-28=-.004n-20\\\\\large\boxed{p=-0.004n+8}$
