Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.

Answer:
Tthe distance between the police station and the fire station is 4 miles
Step-by-step explanation:
Let's call x the distance between the library and the police station
Let's call z the distance between the police station and the fire station
We know that:
miles
The distance (x) between the library and the police station is 3 miles less than twice the distance (z) between the police station and the fire station
This is:
We wish to find the distance z.
Then we equate both equations and solve for the variable z
