let 'x' represent the number of all the passes for the year
350 passes = 70% of all the passes
350 passes = 70% of x
0.70x = 350
by solving we find:
x = 500 passes
9514 1404 393
Explanation:
We can start with the relations ...


-8x - 46 = -6x - 8
-8x + 6x = -8 + 46
-2x = 38
x = -19
The equation:
-8x - 46 = -6x - 8
The solution:
x = -19
Answer:
