Data:

$m=-(203)/(152)\approx-1.3355$
$b=(11227)/(152)\approx73.862$

Equation as a function of D of P

$D(P)=-1.3355\cdot P+73.862$

Answer (6):

• Domain

$(-\infty,+\infty)$

To know how many shirts per month will be demanded if the price is $27, we have to use P = $27:

$D(27)=-1.3355\cdot27+73.862\text{ }\approx37.80$

Answer (7): $37.80
