Answer:
75 posters
Step-by-step explanation:
Given
---- Revenue
--Cost of production
Required
Determine the number of posters that when cost equals revenue
To do this, we simply equate both equations
i.e. 
Collect like terms.

Multiply through by 3



Divide both sides by 8



We have that
n----------> number of cities
the probability that the tourist will visit the cities in alphabetical order is (1/n<span>!)
P=</span>(1/n!)
n!-------------> (7*6*5*4*3*2*1)=5040
therefore
1/5040=0.000198-----------> (five decimal places)--------> 0.00020 (0.020%)
the answer is 0.00020 (0.020%)
There is no answer because you didn’t put some thing after the + so it wouldn’t show nothing
Xintercept is where the line crosses the x axis or where y=0
yintercept is where the line crosses the y axis or where x=0
aka
finding the finding the x intercept is finding the x value when y=0
finding the finding the y intercept is finding the y value when x=0
y=-1/2x-5
xint
y=0
0=-1/2x-5
5=-1/2x
-10=x
(-10,0) is x intercpet
yint
set x=0
y=-1/2(0)=5
y=-5
(0,-5) is yint
xint: x=-10 or at point (-10,0)
yint: y=-5, or at point (0,-5)
