You can put this solution on YOUR website! p(x)= -x/2 + 75
Plug each value of "x" back into the equation and solve.
Values = 2, 7, 9, and 11.
.
p(2)= -(2)/2 + 75 [Plug-in (2) instead of (x) and solve]
p(2)= -(2)/2 + 75
p(2) = $74
.
p(7)= -(7)/2 + 75 [Plug-in (7) instead of (x) and solve]
p(7)= -(7)/2 + 75
p(7) = $71.5
.
p(9)= -(9)/2 + 75 [Plug-in (9) instead of (x) and solve]
p(9)= -(9)/2 + 75
p(9)= $70.5
.
p(11)= -(11)/2 + 75 [Plug-in (11) instead of (x) and solve]
p(11)= -(11)/2 + 75
p(11)= $69.5
