The Friendsville Zoo builds a new rectangular prairie dog enclosure using 65 yards of fencing.  Two sides of the enclosure use a total of 41.50 yards of fencing.  Determine the other 2 equal sides.  

*To get ALL 400 points you MUST WRITE AND SOLVE the equation.  IF you only get 1 part of the answer you get half of the points.  

Equation: 41.50+2L=65 

Answer: 11.75 yards

Corey puts 6 items in each bag when bagging groceries. A customer buys no more than
72 items. Determine how many bags Corey uses. Then interpret the solution.  

*You MUST write, solve, and interpret/explain to get ALL the points.  Hint you will either multiply or divide for your operation once you write your inequality.  

6x ≤ 72; x ≤ 12; Corey uses at most 12 bags.
