Answer:
19
Step-by-step explanation:
To answer this, you will write and equation in terms of the number of adult tickets sold and then solve for a, the number of adult tickets.
$5a + $3.50s = $2517.50
$5a + $3.50(a + 100) = $2517.50
5a + 3.50a + 350 = 2517.50
8.50a -350 -350
<u>8.5a</u> = <u>2167.50</u>
8.5 8.5
a = 255
The number of adult tickets sold was 255, and the number of student tickets sold was 355 (255 +100).
All you have to do is multiply the two numbers together
1.18 x 18.5 = 21.83
3(x-2)=36
3x-6=36
3x=36+6
3x=42
x=42/3
x=14
