To determine the number of times in a month.
Then
Let n = the number of times in a month the bridge is crossed.
Let C = monthly cost
With pass:
C = 30+3.5n
without pass:
C=5n
Then Substitute the values in the place of the C. So, The equation become
30+3.5n=5n
1.5n = 30
n =20
The bridge must be crossed 20 times to make the monthly costs equal.
So, The bridge must be crossed 20 times to make the monthly costs equal.
