Answer:
R(p) = -6p^2 + 60p....
Step-by-step explanation:
Revenue, R = quantity sold * price
Price = p
Quantity sold = q = -6p + 60
R(p) = q*p
where q=-6p + 60
= (-6p + 60) * p = -6p^2 + 60p
Answer: R(p) = -6p^2 + 60p....
Assuming that what you want me to solve is how much she paid for "extra use", the answer is she paid 20 times for the extra charge
47 - 32 = 15
20x .75 = 15
Answer:

Answer:
The answer is 8 feet.
Step-by-step explanation:
Let x = height where the ladder hits the building
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24 feet
Let x = distance from wall:
x^2 + 20^2 = 25^2
x^2 + 400 = 625
x^2 = 225
x = 15 feet
