Atoll 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.]

$33.50

Step-by-step explanation:

The number of vehicles cross the bridge during daytime hours = 20

55% of all vehicles are passenger cars.

The toll bridge charges $1.00 for passenger cars and $2.50 for other vehicles.

The number of passenger cars = 55% of 20

                                                    = 0.55 × 20

                                                    = 11

Then the toll revenue for passenger cars = 11($1.00)

The number of other vehicles = 20 - 11 = 9

Then the toll revenue for other vehicles = 9($2.50)

The expected toll revenue = 11(1) + 9(2.50)

                                             = 11 + 22.50

                                             = $33.50

The resulting expected toll revenue would be $33.50

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

it would more likely be bald eagle because its has more in the box so about 75%.
