Answer:
Explanation:
a. The system of linear inequalities is x + y \geq 3 and 4x + 3y \leq 21.b. The solution is given in the figure.c. The given scenario can happen.
Step-by-step explanation:
Let, I will buy x pounds Blueberries and y pounds Strawberries.
I need to collect at least 3 pounds of fruits.
Hence, x + y \geq 3.
It also given that I can not spend more than $21, that is 4x + 3y \leq 21.
If I will buy 4 pound Blueberries and 1 pound Strawberry, then x = 4 and y = 1.
Now, 4 + 1 = 5 > 3. First inequality is satisfied.
4x + 3y = 4\times4 + 3\times1 = 16 + 3 = 19 \leq 21, Second inequality is also satisfied.
