Answer:
Option A is the right answer.
Step-by-step explanation:
Given information is:
The profit on the sandwiches is $2 for chicken salad and $3 for roast beef.
The amount of bread available is enough for 30 sandwiches.
If chicken salad sandwiches take 3 minutes to prepare and roast beef sandwiches take 5 minutes.
Let x represent the roast beef sandwiches.
Let y represent the chicken salad sandwiches.
The system of equations becomes:
or
..... (1)
....(2)
Substituting (1) in (2)
y = 15
As so,
x = 15
Now we will see the profit;
P = dollars
Therefore, 15 roast beef sandwiches and 15 chicken salad sandwiches should be prepared to maximize the profit.
Hence, the answer is option A.

You need 3 points to graph a quadratic function.
It is advisable that one of these points be the vertex, because the line of symmetry passes through it
Next, you need to find two other points that lie on the curve, replacing an x-value into the function and calculating the y-value. It is easier if these two points are at the same distance from the line of symmetry.
For example, if the quadratic function is y = (x - 4)² + 3, the vertex is located at (4, 3). Replacing with x = 3 into the equation, we get:
y = (3 - 4)² + 3
y = 1 + 3
y = 4
Replacing with x = 5 into the equation, we get:
y = (5 - 4)² + 3
y = 1 + 3
y = 4
Now, we need to connect the points (3, 4), (4, 3), and (5, 4) with a U shape, as follows:
