x=price of one bottle, cost of each bottle =0.5/5=0.1

x - 0.1 = 0.1*5*2

=> x=$ 1.1

I just remeber another MATHJJ.

There have 50 students to take Spanish test, the median score is 74. There have 24 students with the average score 86 above the median score, and 21 students with the average score 60 below the median score. Ask the average score of the 50 students. The number may be not accurate. you just know how to figur out the question.
