Question

Michael took his younger brother to the movies. Michael paid regular price, but it cost $2 less for his brother at the child price. It cost Michael $12 total for the movie.

How much did it cost for his brother?

$5
$7
$6
$10

Answer 1

Let the regular price be r. Then the child price is r − 2 and
r + (r − 2) = 12 → 2r − 2 = 12 → 2r = 14 → r = 7.
Brother’s price = 7 − 2 = $5.

Answer: $5
