Clara earns at least $36.75 but not more than $98 working. She earns $12.25 per hour. The number of hours it takes Clara to earn p dollars is modeled by a function t(p) = p/12.25 What is the practical range of the function?

Divide Lowest and Highest Amounts by 12.25 to find Range.

Explanation:

Lowest Amount is $36.75. When divided by 12.25, 36.75/12.25 = 3 hours.

Highest Amount is $98. When divided by 12.25, 98/12.25 = 8 hours.

So a Practical Range would be 3 <= x <= 8.
