Since we aren't given Jose's age (or the question asked here is incomplete), we can assume we are looking for an expression for "49 decreased by twice Jose's age."
The answer would be:
49 - 2x
where x is Jose's age. Hope this helps.

Answer:
Amy should produce 2 pitchers to maximize profit and the maximum profit will be $18.
Step-by-step explanation:
Amy can produce china pitchers at a cost of $3 each.
She estimates the price function that can be represented by
p = 20 - 4x
Let she sells the number of x pitchers in a week.
Then the selling price of x pitchers will be = $x(20 - 4x)
Cost price of x pitchers = $3x
Profit (P) = Selling price - Cost price
= x(20 - 4x) - 3x
= 20x - 4x²- 3x
= 17x - 4x²
To maximize the profit, ![\frac{dP}{dx}=0](https://tex.z-dn.net/?f=%5Cfrac%7BdP%7D%7Bdx%7D%3D0)
P' = 17 - 8x = 0
8x = 17
![x=\frac{17}{8}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B17%7D%7B8%7D)
x = 2.125
x ≈ 2
Therefore, 2 pitchers should be produced.
Profit = 17x - 4x²
= 17(2) - 4(2)²
= 34 - 16
= $18

x=3
