The toll rates for crossing a bridge are $6.50 for a car and $10.00 for a truck. during a two-hour period, a total of 187 cars and trucks crossed the bridge, and the total collected in tolls was $1,338. how many cars crossed the bridge in the two-hour period?

152 cars crossed the bridge in the two-hour period.

As a total of 187 cars and trucks crossed the bridge, so the number of trucks crossed the bridge

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.......

Thus, the number of cars crossed the bridge in the two-hour period was 152.
