Answer: The solution is is x=7
Step-by-step explanation:
4/3x - 1/3 = 9
+1/3 +1/3
4/3x/4/3 = 28/3
x= 7

Answer:
a) r(x) = 28x
b) p(x) = -x^2 +30x +9
c) 15
Step-by-step explanation:
a) Let x represent the number of items sold. Each sale results in $28 of revenue, so the revenue function r(x) is ...
r(x) = 28x
__
b) p(x) = r(x) - c(x) = 28x -(x^2 -2x -9)
p(x) = -x^2 +30x +9
__
c) The axis of symmetry of ax^2 +bx +c is -b/(2a). Here, the axis of symmetry of the profit function is ...
x = -30/(2(-1)) = 15
15 is the quantity of sales that maximizes profit.
