equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
From the diagram:
Price for 150 bag = $38
Cost per bag = $40 / 150 = $0.25
Also:
Price for 50 bag = $15
Cost per bag = $15 / 50 = $0.30
Difference in price = $0.30 - $0.25 = $0.05
The difference in the price per bag for 150 bags versus 50 bags is $0.05 per bag

X = D/(1 - h)
1 - h = D/x
h = 1 - D/x
D = 400, X = 4000
h = 1 - 400/4000
h = 1 - 0.1 = 0.9
