Question #b9b03

Answer 1

Your `3/10` should be `3/10` of the number of students who cast votes

Explanation:

Let the number of students who cast votes be represented by the variable `color(blue)s`

We are told that
`color(white)("XXX")30%" of " s <= 57`

`color(white)("XXX")3/10 xx s <= 57`

`color(white)("XXX")s <= 57 xx 10/3`

`color(white)("XXX")s <= 190`

Answer 2

`x le 190` `"votes"`

No more than `190` students cast votes.

Explanation:

We know that the candidate receives `57` votes, which are at least `30%` of the total number of votes.

This means that `57` is greater than or equal to `30%` of the total votes.

Let the total number of votes be `x`.

`Rightarrow 30% "of"` `x le 57` `"votes"`

`Rightarrow 0.3 x le 57` `"votes"`

`therefore x le 190` `"votes"`

Therefore, there were no more than `190` students who cast votes.
