Inequality</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let x represent the number of combo A and y represent the number of combo B, hence:
10x + 20y ≤ 400 (1)
Also:
x + y ≤ 28 (2)
The solution is at (16,12). Hence:
Revenue = 21.25 * 16 + 30 * 12 = $700
The maximum revenue is $700 which is at 16 combo A and 12 combo B.
