Brand A coffee costs twice as much as brand B coffee. If a certain blend is 1/2 brand A and 1/2 brand B. what fraction of the cost of the blend is Brand A?
Choose the correct choice from the following answers.
A) a. 1/3 B) b. 2/5 C) 3. 1/2 D) 4. 2/3 E) 5. 3/4
Assume Cost of A= Ca = 200 , Cost of B = Cb=100   The blend contains 0.5 A and 0.55 B ---&gt; Cost of the blend = Cbl = 0.5*200+0.5*100= 
<gadget id="calculator">0.5*200+0.5*100</gadget>
<output>150</output>
150   Thus fraction of A in the blend= 0.5*200/150 = 2/3.   Answer : 4. 2/3
<result>D</result>
