Johnny bought six peanut butter cans at an average price (arithmetic mean) of 37.5¢. If Johnny returned two cans to the retailer, and the average price of the remaining cans was 31¢, then what is the average price, in cents, of the two returned peanut butter cans?
Choose the correct choice from the following choices
A) 5.5	B) 11	C) 47.5	D) 50.5	E) 67.5
Total price of six cans = 6*37.5= 
<gadget id="calculator">6*37.5</gadget>
<output>225</output>
225   Total price of 4 cans= 4*31= 
<gadget id="calculator">4*31</gadget>
<output>124</output>
124   Total rice of two cans= 225 - 124= 
<gadget id="calculator">225 - 124</gadget>
<output>101</output>
101   Average price of two cans= 101/2= 
<gadget id="calculator">101/2</gadget>
<output>101/2 = around 50.5</output>
50.5 c   Another way to do it is this:   Assume that the four leftover cans were of 31c each. The avg was 37.5c initially because the two cans were 36.5c each and were providing another 6.5c of cost to other 4 cans.   So cost of the two cans= 2*37.5 + 4*6.5= 
<gadget id="calculator">2*37.5 + 4*6.5</gadget>
<output>101</output>
101   Avg cost of the two cans= 101/2= 
<gadget id="calculator">101/2</gadget>
<output>101/2 = around 50.5</output>
50.5c   Answer (50.5)
<result>D</result>
