Acompany pays $3.91 million to air a 30- second commercial during a football game that is watched by approximately 115 million potential customers. calculate the cost per second and the cost per customer for this commercial.

Part 1) The cost per second is

Part 2) The cost per customer is

Step-by-step explanation:

Part 1) Calculate the cost per second

we know that

To find out the cost per second, divide the total cost by the time

Let

x ----> the total cost

y ----> the time in seconds

we have

therefore

The cost per second is

Part 2) Calculate the cost per customer

we know that

To find out the cost per customer, divide the total cost by the number of customers

Let

x ----> the total cost

y ----> the number of customers

we have

therefore

The cost per customer is

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
