Among all sales staff at Listco Corporation, college graduates and those without college degrees are equally represented . Each sales staff member is either a level-1 or level-2 employee. Level-1 college graduates account for 10% of Listco's sales staff. Listco employs 72 level-1 employees, 30 of whom are college graduates. How many sales staff members without college degrees are level-2 employees ? Choose the correct choice from the following: A) 108 B) 42 C) 56 D) 32 E) 58
I'm going in on this one.   So let's say that we have the following   So we know that L1 = 72 and that C and L1 = 0.10X , we should set up a double set matrix btw but anyways, I'm just explaining the point with this problem. Now we are told that 0.10x = 30, therefore the grand total is 300. Now we know that L2 is  300 - 72= 
<gadget id="calculator"> 300 - 72</gadget>
<output>228</output>
228. We also learn that C and No C are equally represented thus 150 each. Therefore No C and No L2 will be 150 - 42= 
<gadget id="calculator">150 - 42</gadget>
<output>108</output>
108.   Thus 108 is the correct answer choice
<result>A</result>
