Answer:
Step-by-step explanation:
As for the land requirements, total space must not exceed 400 acres, if each goat (x) needs 2 acres, and each llama (y) needs 5 acres, the inequality is:
As for veterinary care, total expenses must not exceed $13,200, if each goat (x) requires $100, and each llama (y) requires $80, the inequality is:
The system of inequalities that represent this linear programming is:
1. Let A(a,b) be a point in the coordinate axis. The reflection of A with respect to the x-axis is the point A'(a, -b).
2. So the reflection of C(6, 4) is C'(6, -4)
3. Remark, a picture is always helpful when dealing with reflections.
Answer:
(A)
- P(60) = 78.98
- When the bookstore spends $60 on a textbook, the student pays $78.98
Step-by-step explanation:
Given:
P(x) = 1.053(x+0.25x)
P(60) = 1.053(60+0.25*60)
=1.053(60+15)
=1.053(75)
P(60)=$78.98
Since x is the cost from the publisher, when the bookstore spends $60 on a textbook, the student pays $78.98.
<u>The correct option is A.</u>
