At a party of 102 people,17 lb of potato salad is served. a. Write and solve an equation to find how many people each pound of p
Novay_Z [31]

Each pound of potato salad serves 6 people and the average number of pounds of potato salad that each person is served will be \frac{1}{6} pound.

<u><em>Explanation</em></u>

At a party of 102 people, 17 pounds of potato salad is served.

<u>a.</u>  Suppose, each pound of potato salad is served to x number of people.

So, 17 pounds of salad is served to (17*x) or 17x number of people. That means......

17x= 102\\ \\ x= \frac{102}{17}=6

So, each pound of potato salad is served to 6 people.


<u>b.</u>  Suppose, the average number of pounds of potato salad that each person is served is  y

So, the total number of pounds of salad, served to 102 people = (y*102) pounds =102y pounds. That means .....

102y= 17\\ \\ y= \frac{17}{102}= \frac{1}{6}

So, the average number of pounds of potato salad that each person is served will be  \frac{1}{6} pound.
