Answer:
221.90 dollars
Step-by-step explanation:
if it costs 85 dollars for three hours and they are going to rent it for six you mulitply 85 by 2 (to get the cost for 6 hours) and you get 170 then you find 7 percent of 170 (which is 11.90) then you add that to the total. you get 181.90 dollars and then add 40 (which was the tip) and you get 221.90 dollars.
Answer:
The maximum revenue is $900, obtained with 30 people
Step-by-step explanation:
Naturally, the answer should be a number equal or higher than 20, because up to 20 persons, each one pays the same. Lets define a revenue function for x greater than or equal to 20.
f(x) = x*(40-(x-20)) = -x²+60x
Note that f multiplies the number of persons by how much would they pay (here, assuming that there are more than 20).
f is quadratic with negative main coefficient and its maximum value will be reached at the vertex.
The value of the x coordinate of the vertex is -b/2a = -60/-2 = 30
for x = 30, f(x) = 30*(40-(30-20))=30*30=900
So the maximum revenue is $900.
