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).
Answer:
Step-by-step explanation:
y = mx + b
The line y = 3 is a horizontal line with slope zero
y = 0x + 3
All parallel lines will also have a slope zero
a parallel line passing through (-2, 7) will have the equation
y = 0x + 7
y = 7
