There's only information to answer question C.
We can only know that 32 marbles were chosen. (yellow and black)
Why?
To answer the first two questions (a and b), we need to know the total number of marbles, so, we can only answer the last question (c).
We know that 7/10 of the 20 yellow marbles were chosen.
So, calculating we have:
Also, we know that 18 black marbles were chosen, so, the total of marbles chosen is equal to 32 (yellow marbles and black marbles)

Answer:
A function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is
Step-by-step explanation:
We are given that Ryan used 72 mL of food over the course of a 6 day study.
So, He used amount per day =
He used amount per day =12 ml/day
Now we are given that t the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.
So, The equation becomes : f(x)=72-12x
f(x):The amount of plant food remaining
x : The number of days that have passed
Hence a function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x is
