The answer would be 19
Explanation is that 7x3 = 21 -2 = 19
The answer is b sorry if I’m incorrect though
14+2x=62 (x=Pass cost)
-14 -14
(2x=48)/2
x=24
6.50+5.75+1.15x=18
12.25+1.15x=18
-12.25 -12.25
1.15x=5.75 divide both sides by 1.15
x=5
That question mark is filled in with the y-intercept. The y-intercept is where the graph goes through the y-axis. Our graph goes through the y-axis at 1, so the equation is y = 4x + 1
