A caterer provides a conference banquet for a price of $40 per person for 20 or fewer people but will decrease the price by $1 p
mel-nik [20]

Answer:

The maximum revenue is $900, obtained with 30 people

Step-by-step explanation:

Naturally, the answer should be a number equal or higher than 20, because up to 20 persons, each one pays the same. Lets define a revenue function for x greater than or equal to 20.

f(x) = x*(40-(x-20)) = -x²+60x

Note that f multiplies the number of persons by how much would they pay (here, assuming that there are more than 20).

f is quadratic with negative main coefficient and its maximum value will be reached at the vertex.

The value of the x coordinate of the vertex is -b/2a = -60/-2 = 30

for x = 30, f(x) = 30*(40-(30-20))=30*30=900

So the maximum revenue is $900.

saveliy_v [14]

Answer: 1 \frac{3}{16}\ lb

Step-by-step explanation:

You know that Sara has 8 ounces of vanilla yogurt in her cup and her  father’s yogurt weighs 11 ounces. Then, the total ounces of frozen yogurt they buy altogether is:

total_{(ounces)}=8\ oz+11\ oz\\\\total_{(ounces)}=19\ oz

The next step is to make the conversion from ounces to pounds.

You need to remember that:

1\ lb=16\ oz

Therefore:

total_{(pounds)}=(19\ oz)(\frac{1\ lb}{16\ oz})=\frac{19}{16}\ lb

This result expressed as a mixed number, is:

total_{(pounds)}=1\frac{3}{16}\ lb
