Answer:
maximum revenue is 25000
Step-by-step explanation:
The revenue function for a bicycle shop is given by R(x)=x⋅p(x)
Given
Plug in p(x) in R(x)
Now find out the vertex using formula x=-b/2a
a= -0.4, b=200
Plug in 250 for x in R(x)
So maximum revenue is 25000
To get the answer first we have to find full numbers.
We can use proportion
2/3 ----------------------- 375
1 -------------------------- x
Crossmultiply now
2/3*x=375 /:2/3
x=
x=
- its the answer A)
Now we have to find how much were originally on the card.
To get the answer we can just multiply 562 times 1/4.
562*1/4=140 - its the asnwer B)
