Question 200095
The large size requires 12 board-feet of lumber and takes 3 hours to build.
 The small size requires 8 board-feet of lumber and takes 1 hour to build.
 Teresa can use 48 board-feet of lumber each day and plans to spend at most
 9 hours per day building dog houses.
:
3. Model the situation above. Your algebraic model should be a system of
four inequalities.
:
Let L = no. of large dog houses
Let S = no. of small dog houses
:
The material (amt of lumber) inequality
12L + 8S =< 48
:
The labor (no. of hrs worked) inequality
3L + 1S =< 9
:
They want ensure there will be no negative values, therefore:
L => 0
S => 0
:
A total of 4 inequalities
