Answer 2

Sarah drinks 240 oz of energy drinks.

Explanation:

Let us suppose she drinks x calories of drink.

Now, in per 12 oz of drink, the amount of energy = 90 calories

And she drinks 32oz energy drink . Therefore, we have the equation

`(12)/(90)=(32)/(x)`

`12x=90*32\\\\x=(90*32)/(12)\\\\x=240`

Therefore, Sarah drinks 240 oz of energy drinks.
