The table shows the amount of lemon juice needed to make lemonade. Lemon juice (cups) 5 10 20 Servings 35 70 140 Are the two quantities proportional? If so, what is the constant of proportionality?

If we take all of the dived them all (  35 ÷   5 = 7  70 ÷ 10 = 7 140 ÷ 20 = 7) they all equal 7 so in this case it equals 7x  is this a choice?
