Step-by-step explanation:
Answer
Find out the what is the effective cost per year of the extended warranty .
To proof
As given
The extended warranty on a $960 dishwasher is 21% of the purchase price and lasts for eight years.
21% is written in the decimal form
= 0.21
effective cost for the extended warranty = 0.21 × 960
= $ 201.6
= $25.2
Therefore the
effective cost per year of the extended warranty be $25.2
Option (d) is correct .
Hence proved
A minimum of 220 backpacks must be produced to obtain the desired benefits.
Since a company making backpacks charges $ 29.99 for each backpack, and it costs $ 6.45 to make each backpack, and the company can make backpacks in multiples of 10 and there is $ 1,000 in fixed costs, and the company wants to make at least $ 4,000 profit each week, to determine how many backpacks should be produced, the following calculation must be performed:
- 29.99 - 6.45 = 23.54
- 500 x 23.54 - 1000 = 10,770
- 250 x 23.54 - 1000 = 4.885
- 220 x 23.54 - 1000 = 4,178.80
- 210 x 23.54 - 1000 = 3,943.40
Therefore, a minimum of 220 backpacks must be produced to obtain the desired benefits.
