Answer:
38
Step-by-step explanation:
The simplest (almost trivial) solution is to add the two inequalities:
(x +3y) +(3x +2y) ≤ (13) +(25)
4x +5y ≤ 38
The maximum value of P is 38.
_____
Perhaps more conventionally, you can graph the equations, or solve them to find the point of intersection of their boundary lines. That point is (x, y) = (7, 2), which is the point in the doubly-shaded solution space that gives the maximum value of P (puts the objective function line farthest from the origin).
__
In the attached graph, we have been a little sloppy, not applying the constraints that x, y ≥ 0. For the purpose of finding the requested solution, that is of no consequence.

Explanation:
Since we have given that
Speed at which Eugene walked all the way to school = 3 mph
After realizing that she forgot her math book, she ran back
Speed at which Eugene walked back to her house = 7 mph
Let the distance between her house and her school be x
According to question,

Hence,

Step-by-step explanation:
Answer: Weekly rent of Mr. Thomson is = $104.92
Part A: What is Mr. Thompson's yearly rent (using 52 weeks)?
Rent for 1 week = 104.92
Rent for 52 weeks = = $5455.84
Part B: What was the average grocery expense in this time period?
Mr. Thomson purchased groceries on 2/18 for $33.45 and on 3/5 for $28.56
Hence average grocery expense is =
= $31 per week or $62.01 per month
Part C: Mr. Thompson estimates his yearly expense for groceries to be:
The monthly expense for groceries is = $62.01
So yearly expense will be = = $744.12
