Answer:
Explanation:
Let x is number of books (x ≥0)
Let y is the number of DBA (y≥0)
Given that PB = $20 and PD = $40 and consumer has $200 per month, so we can form the inequalities:
200 ≥ 20x+ 40y
So we have a system of inequalities is:
- 200 ≥ 20x+ 40y
- x ≥0
- y≥0
Please have a look at the attached photo, the right triangle are possible solution for the system.
Hope it will find you well
