Answer 2

Option D will be correct.

Explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be
`(333)/(4.41) = (444)/(x)`

⇒
`(3)/(4.41) = (4)/(x)`

Therefore, option D will be correct. (Answer)
