A toll bridge charges $1.00 for passenger cars and $2.25 for other vehicles. Suppose that during daytime hours, 60% of all vehicles are passenger cars. If 30 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

Total revenue by the toll bridge = $45

Step-by-step explanation:

Total vehicles crosses the bridge = 30

Number of passenger cars = 60 % of all vehicles = = 18

Other vehicles = 30 - 18 = 12

Charges for one passenger cars = $1.00

Thus total Revenue by the  passenger cars = 18 × 1 = $18

Charges for other vehicles = $2.25

Total revenue by other vehicles = 2.25 × 12 = $27

Thus the total revenue from the toll bridge = 18 + 27 = $45

I believe the answer is: Prices for goods and services increased, and a dollar bought less than it previously had

In the 1970s, united states was experiencing a period of economic stagnation which later known as called the great inflation of the 1970s.

During this period, the number of unemployment skyrocketed and the value of our currency fall dramatically, which caused an increase in overall products and less amount of products it can obtain with previously same amount.
