Answer:
There are 7 cups of soup left in the pot
Explanation:
Firstly, we need to know the number of cups of soup made.
Since 1 quarts = 4 cups, the number of cups her 4 quarts is would be 4 * 4 = 16 cups
Now she served 1.5( 1 1/2 = 1.5) to 6 people, her total servings is thus 6 * 1.5 = 9 cups
What is remaining is thus 16 cups - 9 cups = 7 cups
