Response:
Andy is mistaken
Step-by-step explanation:
[See attachment for complete question]
The reason Andy is wrong is as follows.
Filling in the empty boxes with any real numbers does not ensure that the expression will qualify as a polynomial.
For example, if the expression is completed as follows:
(5x⁴ + 4x³)(4x^(2.7981) - 6) = A
This output does not represent a polynomial because the powers of x must all be non-negative integers.
Therefore, Andy's assertion is incorrect

Answer:
- The profit can be expressed as 70x + 50
- If 240 phones are sold, the profit amounts to $16,850
Detailed explanation:
The revenue function R(x) is provided as
The cost function C(x) is given as
Profit is calculated by subtracting cost from revenue, expressed as Profit = Revenue − Cost
We substitute the given revenue and cost functions into this formula.
Denote the profit function as P(x).
Therefore, the profit function formula simplifies to 70x + 50
Since x denotes the quantity of phones sold, to find the profit when 240 phones are sold, we substitute x = 240 into the profit expression above.
Hence, selling 240 phones yields a profit of $16,850
