Cost is the amount of spending on a product or service. The lifetime cost of the dishwasher was $1029.8 which is $1030 approximately.
<h3>What is the cost?</h3>Cost is the amount incurred on acquiring a product or using a service. Cost is the value of the product or service.
The lifetime value of an asset is the total expense incurred on the asset from acquisition till disposal.
The lifetime cost of the dishwasher will be the sum of its cost, sales tax, and water and electricity charges for 6 years.
The water and electricity charges are $0.09 and $0.13 per use. The total number of times the dishwasher is used can be calculated as:
The number of use per week are 10, number of weeks in a year are 52, and number of years of use are 6.
Therefore, the water and electricity charges will be:
The cost of the dishwasher will be a combination of its purchase price and sales tax. Therefore:
The lifetime cost of the dishwasher will be:
Therefore the correct option is A.

Answer:
0.0084
Explanation:
For this probability problem, we will have to make use of the normal probability distribution table.
to use the table, we will have to compute a certain value
z = (x- mean) /Standard deviation
z = = 2.39
Probability he has worked in the store for over 10 years can be obtained by taking the z value of 2.39 to the normal probability distribution table to read off the values.
<em>To do this, on the "z" column, we scan down the value 2.3. we then trace that row until we reach the value under the ".09" column. </em>
This gives us 0.99916
Thus we have P (Z < 2.39) = 0.9916
We subtract the value obtained from the table from 1 to get the probability required.
1 - 0.9916 = 0.0084
The Probability that the employee has worked at the store for over 10 years = 0.0084
