Answer:
D, if graphed, it would show a straight line.
Step-by-step explanation:
Because the graph has a relationship (disproving A,) and has 5 cards per pack, (disproving B and C,) we can already rule out the answer choice.
Because the value is constant, (x = y(5)) it will be straight, thus giving you your answer. You can even graph the values for a clear representation.
Use the proportion 8/64 = 12/y. Cross multiply to get 8y = 768. Divide both sides by 8 to get y=96
Numbers 3,4,5 make this inequality true
8+3=11
8+4=12
8+5=13
10.5 L = 10500 mL
# times = 10500/350 = 30 times
