Answer:
the unit rate is 30 miles 1 gallon
x = students = $10
y = non students = $12
total tickets = 150
Equations
x + y = 150
10x + 12y = 1440
x = 150 - y
10(150 - y) + 12y = 1440
1500 - 10y + 12y = 1440
2y = 1440 - 1500
2y = -60
y = -60/2
y = 30
x = 150 -
It is not . There are multiple x values for the y values.
You just plug 6 in for x so
5(3)(6)-4
15(6)-4
90-4
86
hope it helps
