Chapter 4.5, Problem 15PPE

To determine

To write: a function rule that represents the given situation.

Explanation of Solution

Given information:

The a is left in $8-oz$ bottle after each batch b decreases by $\frac{1}{6}oz$

Given that,

  $8-oz$ bottle decreases by $b\frac{1}{6}oz$

  $=8-b\frac{1}{6}$

a is left in the bottle .

Then, the rule is

  $a=8-b\frac{1}{6}$

Hence, the function rule representing given situation is $a=8-b\frac{1}{6}$
