55x+35(500-x)≤20000, the solution is: x≤ 125.
If the profit from selling these two drinks in the mall is Y, then
y=(63-55)x+(40-35)(500-x)
=3x+2500
∵3>0,
∴y increases with the increase of X. To maximize Y, X should take the maximum value, and the maximum value of X is 125.
Therefore, when x= 125, the maximum value of y is 3× 125+2055=2875 yuan.
