a.
To write a system of inequalities to model the different number of trays Tonya can bake.
a.

Answer to Problem 13STP
Explanation of Solution
Given:
Suppose Tonya is baking cookies and muffins for a bake sale. Each tray of cookies uses 5 cups of flour and 2 cups of sugar. Each tray of muffins uses 5 cups of flour and 1 cup of sugar. She has 40 cups of flour and 15 cups of sugar available for baking. Tonya will make $12 profit for each tray of cookies that is sold and $8 profit for each tray of muffins sold.
Calculation:
Let
The following is the system of inequalities −
b.
To graph the system of inequalities.
