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
in STR,
ST=SR
therefore, t=r(angles opposite equal sides of a triangle are equal)
T=73
C+73+73=180(ASP of triangle)
C=34
The answer is B. Kristine is exactly 9 inches taller than Colleen
