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.

Explanation

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

a. 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.

b. 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.
