Answer

28 students voted for the break. You can see that Carl's answer is not reasonable because his answer exceeds the total number of students who voted.

Work Step by Step

$\frac{8\ yes\ votes}{10\ students} = \frac{x\ yes\ votes}{35\ students}$ $10x = 8\times35$ $\frac{10x}{10} = \frac{280}{10}$ $x = 28$
