Answer 2

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Jane mixes 3 pints of blue paint with 4 pints of red paint to get her desired color.

So, the ratio will be

`3:4`

We have 16 pints of red paint and we have to find the pints of blue paint 'say x'.

According to question,

Since there is "direct variation" . So,our equation becomes,

`(3)/(16)=(4)/(x)\\\\x=(16* 4)/(3)\\\\x=(64)/(3)\\\\x=21.34`

Hence, Option 'C' is correct.
