The first thing to be done is to convert the 2 tons into pounds.
1 pound is equal to 0.0005 tons (US). So, 2 tons divided by 0.0005 will give us the aluminium pounds per week that are processed by the Recycling Centre B.
=4000
Recycling Centre B processes 4000 pounds/week. In order to compare to Recycling Centre A, we need to find the rate in pounds per hour. To do so divide the 4000 pounds by 168 (24×7 = number of hours in a week).
≈23.8
The Recycling Centre B processes about 23.8 pounds/hour whereas the Recycling Centre A processes 100pounds/hour.
First you have to subtract 1.3 from 0.75 which equals -0.55. Then you have to add 3/7 to 2 which equals 2 and 3/7. Then you divide 2 and 3/7 by -0.55 which equals 0.9785 and that’s your answer. Sorry I don’t know the answer for the second problem but I hope this helped.
