Question

Admission for a play is $9 for adults and $5 for students. The first night, the box office sold twice as many adult tickets as student tickets. The second night, the number of each type of ticket sold was three times the number sold the first night. Which expression can be used to determine the total amount of money received for sales of tickets on both nights? Let a be the number of adult tickets sold and s be the number of student tickets sold.

Answer 1

= 72a + 20s

Explanation:

Given that;

a = number of adult tickets sold

s = number of student tickets sold.

According to given condition:

For first night;

=2(9a) + 5s

=18a + 5s

For second night:

= 3*18a + 3*5s

= 54a + 15s

Expression for total money of both nights:

= (18a + 5s ) + (54a + 15s )

Adding same terms:

= 72a + 20s
