Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.

Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78

Cost of electricity = $0.18

Now in the case of electricity,

spending on Brand A = 635 $\times$ 0.18 = $114.3

spending on Brand B = 582 $\times$ 0.18 = $104.76

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

Answer:

2 tons and 1824 pounds

Step-by-step explanation:

Ton= 2,000 pounds

We know that 2,000 will go into 5824 twice, resulting in 4,000. Subtract 4,000 from 5,284, and you will have an answer of 1284. 1,284 does not go into a ton, therefore you have a remainder of 1,284 pounds.
