Final answer:
A system of inequalities representing Travis's budget for perennial and annual flowers is x ≥ 144, y ≥ 90, and x + y ≤ 300, where x is the amount spent on perennials and y is spent on annuals.
Step-by-step explanation:
The student has asked to define a system of inequalities that represents the budget problem faced by Travis, who has a budget constraint for buying perennial and annual flowers. Given that Travis has $300 to spend, wants at least 8 perennial flowers at $18 each, and at least 6 annual flowers at $15 each, we can establish the following system of inequalities:
- x ≥ 8 × 18
- y ≥ 6 × 15
- x + y ≤ 300
Where x represents the amount spent on perennial flowers and y represents the amount spent on annual flowers.
