(a)
Answer to Problem 29E
Explanation of Solution
Given information:
The amount spends on $21 on fruit. The blue berries cost $3 per pound. It is required atleast 3 pounds to make the fruit muffins.
Let:
Set up the inequalities:
At least a total 3 pounds
At most $23 on cost
Restrict the graph to positive x & y values since negative values do not make sense in this real-life context.
Graph the equations:
The solution is the dark shaded area:
Conclusion:
The graph to positive x & y values since negative values do not make sense in this real-life context.
(b)
To find: The solution of the system.
(b)
Answer to Problem 29E
3 Pounds of blueberries & 1 pound of strawberries
Explanation of Solution
From the graph the point (3, 1) lies under the solution part so it is one solution of the system.
(c)
To use: The graph to check if 4 pounds of mulberries and 1 pound of strawberries fits in the solution.
(c)
Answer to Problem 29E
