Step-by-step explanation:
The bill total + 20% of the bill total must be less than or equal to $60.
So we have the inequality:
x + 0.20x ≤ 60
1.20x ≤ 60
x ≤ 60/1.20
x ≤ 50 dollars.
Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.
