Question

7.) Adult tickets for Disney on Ice are $6.50 while a child's ticket is only $2.50. At Tuesday night's

performance, 435 people were there in attendance. The box office brought in $1667.50 for that evening.
How many of each type of ticket were sold?

Answer 1

Adult tickets: 145

Child tickets: 290

Explanation:

Let x = adults; y = children

`\left \{ {{x + y=435} \atop {6.50x+2.50y=1667.50}} \right.`

=> x = adults = 145

y = children = 290
