# The school band sold 200 tickets to their concert. If 90 of the tickets were adult tickets, what percent of the tickets sold were adult tickets?

#### Answer:

The $90$ adult tickets sold were 45% of the $200$ tickets sold to the concert.

#### Explanation:

Since $90$ tickets out of $200$ were adult tickets, the percentage (represented as $x$) can be calculated by this equation:

$200 \times \frac{x}{100} = 90$

$2 \cancel{200} \times \frac{x}{\cancel{100}} = 90$

$2 x = 90$

Divide both sides by $2$.

$x = 45$
