Answer:
The number of extra glasses required is 3954.
Step-by-step explanation:
Total volume of water in a bottle = 370 liters
Number of glasses, N = 46
capacity of each glass = 90 ml = 0.09 liter
The volume of water required to fill 46 glasses is
= 0.09 x 46 = 4.14 liter
The amount of water left = 370 - 4.14 = 355.86 liter
The number of extra glasses required to fill is
n = 355.86/0.09 = 3954
So, the number of extra glasses required is 3954.
The break even point is when profit is equal to zero, or in this case when p(x)=0
4x^2-28x+40=0
4(x^2-7x+10)=0
4(x^2-2x-5x+10)=0
4(x(x-2)-5(x-2))=0
4(x-5)(x-2)=0
So the break even points are when x=2 and 5, which is when 2000 and 5000 units are sold.
