Acompany can sell 2000 magazine subscriptions at $40 each. for each $5 increase in the price, it will sell 200 fewer subscriptions. what subscription price will provide the maximum revenue for the company? $55 $40 $45 $50

ANSWER

The subscription price of $45 provides the maximum revenue for the company

EXPLANATION

When the price is $, the company sells quantities.

The total revenue accrued

When the price increases to $ the quantity sold will decrease by 200 magazines which is

The total revenue accrued

dollars

When the price increases to $ the quantity sold will decrease by 200 magazines again which is

The total revenue accrued

dollars

When the price increases to $ the quantity sold will decrease by 200 magazines which is

The total revenue accrued

dollars

Hence a subscription price of $45 provides the maximum revenue for the company.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
