Question

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?
All multiples of 12.25 between 36.75 and 98, inclusive.
All real numbers from 3 to 8, inclusive.
All real numbers.
All real numbers from 36.75 to 98, inclusive.

Answer 1

All real numbers from 3 to 8, inclusive.

Explanation:

Answer 2

`36.75 \leq p \leq 98`

`t(p)= (p)/(12.25) \\t(36.75)= (36.75)/(12.25) =3 \\t(98)= (98)/(12.25) =8 \\3 \leq t(p) \leq 8`
All real numbers from 3 to 8, inclusive.
