A company that manufactures and sells consumer video cameras sells two versions of their popular hard disk camera, a basic came

saul85 [17]

Answer:

The percentage of customers who buy an extended warranty is 33%.

Step-by-step explanation:

In this problem, we have these following percentages.

35% of the customers select the basic camera.

This also means that:

65% of the customers select the deluxe version. (Since you can buy only two versions of the hard disk camera and the sum of the percentages is 100%).

20% of those who select the basic camera also purchase the extended warranty.

40% of those who select the deluxe version also purchase the extended warranty.

What is the percentage of customers who buy an extened warranty?

$P = P_{1} + P_{2}$

$P_{1}$ is the percentage of those who buy the basic version with the extended warranty. So it is 20% of 35%. So

$P_{1} = 0.20*0.35 = 0.07$

$P_{2}$ is the percentage of those who buy the deluxe version with the extended warranty. So it is 40% of 65%. So

$P_{2} = 0.40*0.65 = 0.26$

$P = P_{1} + P_{2} = 0.07 + 0.26 = 0.33$

The percentage of customers who buy an extended warranty is 33%.
