Dangerous goods 5. General waste Q1. The manager tell you that each bin Lakes roughly 20 mimit to fully collect, he wants you to help him figure out how many workers are required to clean the site in two hours Q2. The manager returns, he has a new problem: two of his workers have gone home sick. He wants to know how much quicker now must each bin be collected in order to meet the two hour deadline? Q3. The bin manager has another issue, he tells you that in order to pay his workers he uses this equation to figure out their total pay for the month: "I first add the number of hours worked with four times the number of bins collected. Then I multiply this with the number of hours worked again but I add to it two times the number of days vorked" In other words, he works out their pay using this formula: (+ 4y)(+2). You tell him that there is an easier way to read this by multiplying it out, what would you get if you multiplied out these brackets? Q4. One of the workers has worked 30 hours, collected 20 bins and worked for 8 days, how much would his total pay be for the month? The manager realises that using this formula the workers are making too much money, you suggest that instead his formula should be (I + y) (x+ Q6. The manager would like to know what this formula is when multiplied out? Q6. Also, how much does that same worker now make using this new for 11) 1! 01:10 PM - (7 marks) The bin collectors are running on tight deadlines, their manager needs his schedule sorted so he's come to you for help.
