A company pays project contractors a rate of a dollars for the first hour and b dollars for each additional hour after the first, where a > b.
In a given month, a contractor worked on two different projects that lasted 6 and 8 hours, respectively. The company has the option to pay for each project individually or for all the projects at the end of the month. Which arrangement would be cheaper for the company and how much would the company save? Select the correct option:
A) Per month, with savings of $(5a + 5b)  B) Per month, with savings of $(5a - 5b)  C) The two options would cost an equal amount.  D) Per project, with savings of $(5a + 5b)  E) Per project, with savings of $(5a - 5b)
Per Project, company will pay as follows:   For 6 hours work = a+5b   For 8 hours work = a+7b   Total = 2a+12b   Per Month, company will pay for 14 hours work = a+13b   Total per contract - total per month   6a+8b - (a+13b)   5a-5b   Since a&gt;b Amount 6a+8b(per contract amount) &gt; a+13b (per project amount) by 5a-5b.   Hence per month payment will be cheaper by 5a-5b .   OA Per month, with savings of $(5a - 5b)
