You can spend at most $21 on fruit. blueberries cost $4 per pound, and strawberries cost $3 per pound. you need at least 3 pounds of fruit to make muffins.

a. write and graph a system of linear inequalities that represents the situation.
b. identify and interpret a solution of the system.
c. use the graph to determine whether you can buy 4 pounds of blueberries and 1 pound of strawberries.

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, .

It also given that I can not spend more than $21, that is .

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.

, Second inequality is also satisfied.
