How many sales staff members without college degrees are level-2 employees ?	Choose the correct choice from the following answers:	A) 46	B) 48	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 0.1x = 20, therefore the grand total is 200. Now we know that L2 is  200 - 72= 
<gadget id="calculator"> 200 - 72</gadget>
<output>128</output>
128. We also learn that C and No C are equally represented thus 100 each. Therefore No C and No L2 will be 100 - 52= 
<gadget id="calculator">100 - 52</gadget>
<output>48</output>
48.   Thus 48 is the correct answer choice
<result>B</result>
