Answer:
18, 23
Step-by-step explanation:
a. We know that W = 5 and D = 3 so:
P = 3W + D = 3 * 5 + 3 = 18 points
b. We know that P = 50 and D = 14 and that we are solving for W so we get:
50 = 3W + 14
36 = 3W
W = 12 which means the losses are 35 - 12 = 23.
The equation would be 5+4x=7x+11
Which comes out to:
x = - 2
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.
Answer:
20
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
20 = c
The length of BC = 20
Answer:
Jerry does 
cases per hour (Rounded to 2 decimal places). As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.
Step-by-step explanation:
to find the number of cases per hour, we have to divide the number of cases by number of hours taken for those cases,
Number of cases per hour = 
=
cases per hour
=
cases per hour
=
cases per hour
= cases per hour (Rounded to 2 decimal places)
As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.
