Anastaziya [24]

Answer:

\frac{1}{4} lbs/person

Step-by-step explanation:

Here is the complete question: Find the rate of change for the situation:

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.

Given: 1st situation, A chef cook 9 lbs chicken for 36 people.

           2nd situation, chef cook 17 lbs chicken for 68 people.

∴ 1st situation, weight of chicken per person= \frac{9\ lbs}{36\ person} = \frac{9}{36}

  Weight of chicken per person= \frac{1}{4} lbs/ person

2nd situation, weight of chicken per person= \frac{17\ lbs}{68\ person} = \frac{17}{68}

Weight of chicken per person= \frac{1}{4} lbs/ person

In both the situation chef cook same amount of chicken per person, which is \frac{1}{4} lbs/ person

∴ Rate of change is \frac{1}{4} lbs/ person
