I think that the correct function in your question should be y = 60x⁻¹ + 0.625x.
With that said, the answer is A. <span>0 < x < ∞
By the process of trial and error of the choices, we can see that this choice satisfies the equation. Take note that y models moose population, so y should always be positive. </span>
Given:
Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.
He is only allowed to work 13 hours total per week.
He wants to make at least 65 dollars.
To find:
The system of inequalities to represent this situation.
Solution:
Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.
He is only allowed to work 13 hours total per week. It means sum of x and y must be less than or equal to 13.
![x+y\leq 13](https://tex.z-dn.net/?f=x%2By%5Cleq%2013)
He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.
![4x+7y\geq 65](https://tex.z-dn.net/?f=4x%2B7y%5Cgeq%2065)
Number of hours can not be negative.
.
Therefore, the required system of inequalities contains some equations,
and
.
