Answer:
152 cars crossed the bridge in the two-hour period.
Step-by-step explanation:
Suppose, the number of cars crossed the bridge was [tex]x[/tex]
As a total of 187 cars and trucks crossed the bridge, so the number of trucks crossed the bridge [tex]=187-x[/tex]
The toll rates are $6.50 for a car and $10.00 for a truck and the total collected in tolls was $1,338.
So, the equation will be.......
[tex]6.50x+10.00(187-x)=1338\\ \\ 6.50x+1870-10x=1338\\ \\ -3.50x=1338-1870\\ \\ -3.50x=-532\\ \\ x=\frac{-532}{-3.50}=152[/tex]
Thus, the number of cars crossed the bridge in the two-hour period was 152.
