A company estimates that 1% of their products will fall after the original warranty period but within 2 years of the purchase, with a replacement cost of $480.
If they want to offer a 2 year extended warranty, what price should they charge so that they'll break even (in other words,
so the expected value will be 0)
(round to the nearest cent)

They should charge a price of $4.85 so that they'll break even.

Step-by-step explanation:

The expected value will be the sum of the net values multiplied by it's probabilities.

1% of their products will fall after the original warranty period but within 2 years of the purchase, with a replacement cost of $480.

So in 1% = 0.01 of the cases, the company loses $480. That is, a net value of -480.

In 99% = 0.99 of the cases, the company makes x.

The expected value is 0.

We have to find x.

So

They should charge a price of $4.85 so that they'll break even.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
