Question

Mark and Nancy are making punch for a party and are using two types of juice: pineapple and papaya. The total number of quarts must be more than 9 but less than 15. They should use at least 4 quarts of each type. We want to find out how many quarts of each juice they should buy.
List any 3 ordered pair solutions for the system of equations which represent this problem.

Answer 1

x= quarts of pineapple
y= quarts of papaya
\[9<x+y<15\]\[x \ge 4\]\[y \ge 4\](5,6) is one solution because\[x=5 \ge 4\]and\[y=6 \ge 4\]and \[9<5+6<15\]from this information you should be able to find two more yourself.
