Replace present refrigerators with similar refrigerators at a cost of $20 x 106. option 2. replace present refrigerators with lake-source cooling at a cost of $50 x 106. however, the lake-source cooling would save 1.5 x 106 $/year in electricity costs. assume a 10-year straight-line depreciation for both options. do you agree with the utilities engineers' conclusion that lake-source cooling is economically advantageous?

No, Lake source cooling is not economically advantageous.

Explanation:

The cost of the lake source cooling is S30 greater than the cost of the refrigerator.

Though the lakes source option will bring additional income of S2400 for ten years this will only reduce it's cost to S2900 and this is still higher than the total cost of the refrigerator option of S2,120.

The straight line depreciation option on both options will not change this decision since it will have the same effect on both options.

there is a app that you show the question and it anwsers it in the app store

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.
