A. There are 20 grams of protein in 2 cups of milk.

B. The unit rate of protein in milk is 13.5 grams per cup.

C. There are 8 grams of protein per cup of milk.

D. There are 1.5 grams of protein in 12 cups of milk.

Answer 1

I believe the answer is C

Answer 2

There are 8 grams of protein per cup of milk.

C is correct.

Explanation:

We are given a graph of Protein( gram) Vs Amount of milk (cups).

In graph

x-axis represents Amount of Milk (cups)

y-axis represents Protein (grams)

In graph, Line passing through (0,0) and (1.5,12)

Using two point we will make equation of line.

`y-0=(12-0)/(1.5-0)(x-0)`

`y=8x`

`P=8a`

Now, we will check each option.

Option A: Put a=2 and P=20

`20=8(2)`

`20\\eq 16`

False

Option B: Put a=1 and P=13.5

`13.5=8(1)`

`13.5\\eq 8`

False

Option C: Put a=1 and P=8

`8=8(1)`

`8= 8`

True

Option D: Put a=12 and P=1.5

`1.5=8(12)`

`1.5\\eq 96`

False

Hence, There are 8 grams of protein per cup of milk.
