The development fee p can be modeled by the equation p=-400q+9600 where p is the price the company charges and q is the number of contracts they get. The total revenue R ISeeYou obtains by signing q contracts is found by using the function: . The cost ISeeYou Productions can be found by using the following function: C(q)=800q+16000. The monthlhy profit of Express ISeeYou Productions if found with the next function:
. ISeeYou should sign 2 or 20 contracts to break even.
a) In order to solve part a of the problem, we will suppose the price will have a linear relation with the amount of contracts they signed, so we need to find two points to build this function.
We know that when signing 6 contracts, the company charges $7,200, so our first point will be:
(6, 7200)
we also know that the company signs 14 contracts when they charge $4,000. So our second point is:
(14, 4000)
so we can use these points to find the slope of the line by using the
slope formula:
so the slope is:
m=-400
We can now use one of those points and the slope to find the function for the price, so we get:
if we used the point: (6, 7200) we get:
which can now be simplified:
p=-400q+2400+7200
so the price function is:
p=-400q+9600
b) In order to find the revenue equation we need to multiply the price equation by the amount of contracts they signed in a month, so we get:
R(q)=pq
c) The cost can be found by adding the fixed cost and the variable cost, so we get:
C(q)=800q+16000
d) The profit is found by subtracting the montly cost from the monthly revenue, so we get:
P(q)=R(q)-C(q)
so
so we can now simplify our function to get:
e) In order to find the number of contracts for the company to break even, we need to find the q contracts that will give a profit of $0 so we set the function of the previous part of the problem equal to zero so we get:
we can start by factoring a -400 from the left side so we get:
we can divide both sides of the equation into -400 to simplify the equation so we get:
and now we can factor the left side of the equation to get:
(q-20)(q-2)=0
we can now split this into two equations to get:
q-2=0 and q-20=0
so our two answers are:
q=2 and q=20
the company will break even when signing 2 and 20 contracts.
In the attached picture you will be able to see the break even points on the graph of revenue and cost.
