Final answer:
The ice-cream shop needs to find a viable combination of ice cream and frozen yogurt that satisfies the given constraints.
Step-by-step explanation:
The ice-cream shop has the following constraints:
- x > 0
- y > 0
- 3x + 7y < 200
- y ≥ 2x − 20
We need to find the point (x, y) that satisfies these constraints. To do that, we can graph the inequalities on a coordinate plane and find the region that satisfies all the constraints. The viable combination of ice cream and frozen yogurt the shop can make in a day and satisfy the constraints is the region that is shaded.
