Answer:
The total cost
in dollars of going to the baseball game for
people of a family can be given as:

Step-by-step explanation:
Given:
At a baseball game:
Cost of car parking = $5
Cost per ticket = $21
To write an equation in the form of
representing the total cost of going to the baseball game.
Solution:
The total number of people in the family is = 
Using unitary method to find the cost of tickets for
persons.
If 1 ticket costs = $21
<em>Then,
tickets will cost in dollars</em><em> = </em>
Fixed rate for car parking = $5
Thus, the total cost
in dollars of going to the baseball game for
people of a family can be given as:

Answer:
The number of elephant ears that must be sold to maximize profit is 400.
Step-by-step explanation:
Given that,
The profit that a vendor makes per day is given by
P(x)= - 0.004x² +3.2 x -200
where x is number of elephant ears.
P(x)= - 0.004x² +3.2 x -200
Differentiating with respect to x
P'(x)= - 0.008x+3.2
Again differentiating with respect to x
P''(x) = -0.008
For maximum or minimum P'(x)=0
- 0.008x+3.2=0
⇒0.008x=3.2

⇒ x = 400

Since at x=400, P''(x)<0, the profit is maximize.
P(400) = -0.004×400²+3.2×400-200
=440
The number of elephant ears that must be sold to maximize profit is 400.
