{13,14}
Step-by-step explanation:
Let
x ----> number of hours per week of tutoring
y ----> number of hours per week of landscaping
we know that
She can work no more than 17 hours
so
-----> inequality A
She must earn at lest $240
The term " at least" means, "greater than or equal to"
----> inequality B
If Autumn worked 3 hours landscaping
then
substitute in the inequality A and in the inequality B
<em>Inequality A</em>
Inequality B
The solution of the system is the interval {12.75,14]
All possible values for the number of whole hours tutoring that she must work to meet her requirements are
