Answer:
13.333% of 3 is 4.
Step-by-step explanation:
Take missing value = x
x% of 3 = 4
x/100 × 3 = 4
3x/100 = 4
3x = 400
x = 400/3
x = 13.333

Answer:
18.2%
Step-by-step explanation:
For decimals, just move the point two times to the right.
Since a $5 decrease in price increases customers by 20 we can say that we have two points:
(125,100) and (120,120), from these we can find the slope or rate of change of customers as a function of price...
m=20/-5
m=-4
m=-4
c(p)=-4p+b, now we can use (125,100) to solve for b
100=-4(125)+b
100=-500+b
600=b, so our number of customers as a function of price is:
c(p)=600-4p
Revenue will simply be the number of customers times the price charged per customer...or p*c(p):
r(p)=600p-4p^2
We can find price that creates maximum revenue by finding when the derivative is equal to zero...
dr/dp=600-8p
dr/dp=0 only when
0=600-8p
8p=600
p=75
So the price that maximizes revenue is $75.
