A. 14%
B. 13%
C. 30%
D. 54%
+37146 Well, according to the chart 13 out of 90 want a 86 inch LCD television 13/90 = 14.4% or 14% rounded
Though the question asks what percent of the warehouse should be stocked with 86-inch televeisions ....it doesn't really ask for 'LCD televisions' (even though they are referred as 'on sale')...it only asks for 86 inch televisions which would be 24/90 or 26% (but this is not an answer option.....so I suspect they MEANT to ask about 86 - inch LCD televisions).
