- This part is similar to part 1, but instead of being given the number of repipes and tankless installs per 40 hour workweek, you are given the time per repipe or tankless install, in hours. Each worker at Derby Plumbing Services works 40 hours. The productivity of the six workers differs from part 1. ITT Hours per tankless Worker Hours per repipe install Austin 4.5 6.5 Cody 5 8 Dallas 3 4.5 Lincoln 4.5 Pierre 2.5 5 Victoria 12. If each worker split their time equally between repipes and tankless installs (i.e., devoted 20 hours to each), how many repipes could the company complete if all workers work a 40 hour week? (Partial repipes are allowed; enter your answer to one decimal place.) 13. If each worker split their time equally between repipes and tankless installs, how many tankless installs could the company complete if all workers work a 40 hour week? (Partial tankless installs are allowed; enter your answer to one decimal place.) 14. If you used the concept of comparative…Quantitative Reasoning 2. Until Summer 2012, if you wanted an iPhone you needed to lock into a two-year contract. Then some mobile companics started selling the iPhone and letting you choose your own plan, with no contract. You can use the ideas from chapter 7 to make a quantitative comparison. Virgin Mobile began selling a 16 GB iPhone 4S for $649.99, with no plan or contract. They offered a $55 per month "unlimited" data plan (in fact it was not unlimited, as once you got past 2.5 GB of data they slowed the phone speed down considerably). If you purchased the phone through Sprint, it cost just $149.99. However, you had to sign up for a two year contract. The least expensive option was $79.99 with what they called unlimited data. (a) For each plan, find a linear function what shows how the total cost of the phone depends on the number of months you have it. • Virgin Mobile: y= . Sprint: y= (c) Clearly the Virgin Mobile plan is more expensive at first. When does it become the less…BD.2 Calculate profit: word problems 2W3 Learn with an example v With her grandmother's help, Eve learned to make quilts.

- How should be the process to follow on this question, please? You buy 2,300 pens at the beginning of the school year. You estimate that 20% of them will have to be put on your "discount plate" at the end of the term on which everything is priced at $1. Generally, about 32% of the "discount plate" items will be damaged or broken and will have to be thrown away. The pens cost you $1.27 per pen and you want an average markup of 37% based on selling price. At what price must they start selling the pens?A certain city's power company charges their residents for electricity usage on a daily basis. There is a basic charge of 11.57 cents. For each day the first 10 kWh cost 4.81 cents per kWh and any additional kWhs are 9.69 per kWh. (A kWh, or kilowatt-hour, is a unit of energy.) (a) Complete the following table using the information provided above. kWhkWh 0 5 10 15 20 cost (dollars)cost (dollars) kWhkWh 25 30 35 40 cost (dollars)cost (dollars) (b) We can define a piecewise function f(x)f(x) where xx is the kWh used in a day and f(x)f(x) is the cost, in dollars.

Using a very aggressive marketing strategy they have been able to increase their annual revenue by approximately $10 million over the past 10 years. But increased competition has slowed their growth rate in the past few years. The annual revenue, in millions of dollars, for the previous 10 years is contained in the Excel Online file below. Construct a spreadsheet to answer the following questions.
- 2. Write a program that models a cashier at a store. The program will take two numbers as input. Firstly, the cost of an item ($20.00 or less). Secondly, the amount of money given to the cashier ($20.00 or less). The program should output the change given in 10 dollar bills, 5 dollar bills, 1 dollar bills, quarters, dimes, nickels, or pennies. You should output the highest denominations possible. For example, if the item costs $5.20 and the cashier is given $10 then the change should be 4 dollar bills 3 quarters 1 nicklef. Now suppose that Lynn contributes nothing to her retirement fund for eight years and then begins contributing $3,000 annually until age 60. How much of her salary would she have contributed to this retirement plan and how much money could she expect to have accumulated at age 60? f?both sheets are for the same problem.
