Answer:
Step-by-step explanation:
Let the student tickets sold = x
Let the non-student tickets = y
x + y = 311
0.5x + 1.5y = 385.5 Multiply the second equation by 2
x + 3y = 771 Subtract2y the first equation
<u>x + y = 311</u>
2y =460
y = 230
x then will equal 311 - 230 = 81
Check
81 * 0.5 = 40.5
<u>230 * 1.5 = 345</u>
Total = 385.5 just as it should
1:3
Lowest possible simplification.
1. Slope = 1/4
Point = ( 1, 1 )
2. Slope = -3
Point = ( 3, -20 )
4320
