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:

x+y=30 or x=30-y   ..... (1)

5x+3y=120     ....(2)

Substituting (1) in (2)

5(30-y)+3y=120

150-5y+3y=120

150-2y=120

150-120=2y

2y=30

y = 15

As x=30-y so, x=30-15

x = 15

Now we will see the profit;

P = (3\times15)+ (2\times15)=45+30=75 dollars

Therefore, 15 roast beef sandwiches and 15 chicken salad sandwiches should be prepared to maximize the profit.

 Hence, the answer is option A.

F(x)=x^2+4x and g(x)= 2x+2, find f(5)+ g(6)
Lubov Fominskaja [6]
F(5) = 5² +4*5=25+20 = 45
g(6) = 2*6 +2 =12+2=14

f(5) + g(6)
= 45 +14 =59
