Here are the answer I got:
3 quart 1 pt= 7 pints
2 gallons I quart =  9 quarts 
1 qt I cup = 17 cups 
6 quart 3 cups -= 27 cups 
21 pints 1 cup -=  43 cups 
1 gallon 7 cups=  23 cups 
2 gallons 8 pints = 3 gallon 
3 pints 6 cups= 12 cups 
4 gallon 3 quarts = 19 quarts 
3 quart 2 cups = 14 cups 
8 quart 1 pint = 17 pints 
2 quart 3 cups =  7 cups 
9 quart 4 pints = 11 quart 
7 quart 2 cups = 16 cups 
1 gallon 4 pints = 12 pint 
1 gallon 7 pints = 30 cups 
3 gallon 3 pints = 27 pints 
5 quart 2 cups = 22 cups
2 gallon 4 cups = 36 cups
Hope this helps!

Graph C is the only graph that represents a function.

Remember the vertical line test, draw a vertical line through any y point on your graph, if that line intersects the graph more than once, your graph does not represent a function.
