I think the answer is A. But I’m not fully sure
Answer:
x = 11/9
Step-by-step explanation:
Eliminate parentheses, add 16x, subtract 21.
7(3 -x) = 8(4 -2x) . . . . given
21 -7x = 32 -16x . . . . . eliminate parentheses using the distributive property
9x +21 = 32 . . . . . . . . add 16x
9x = 11 . . . . . . . . . . . . subtract 21
x = 11/9 . . . . . . . . . . . .divide by the coefficient of x
The maximum revenue is $700 which is at 16 combo A and 12 combo B.
<h3>
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.
