A toll bridge charges $1.00 for passenger cars and $2.50 for other vehicles. Suppose that during daytime hours, 55% of all vehicles are passenger cars. If 20 vehicles cross the bridge during a particular daytime period, what is the resulting expected toll revenue? [Hint: Let X = the number of passenger cars; then the toll revenue h (X) is a linear function of X.]

Clarence Rollins · Answer 1

The number of passenger cars that crossed the bridge is the product of 20 and 0.55 which is equal to 11. Hence, the number of other vehicles is 9. The revenue is calculated below,

11 ($1) + 9 ($2.50) = $33.5

Thus, the total revenue of the toll bridge is $33.5.
