The toll on a bridge is $ 1.00 for cars and $ 2.50 for trucks. in one hour, a toll operator raises a total of $ 105 in tolls. write an equation that represents the relationship between the number of cars, c, and the number of trucks, l, that could have gone through this toll.

the equation representing the relationship between c and L is

c + 2.5L = 105

Step-by-step explanation:

Let c represent the number of cars that could have gone through the toll.

Let L represent the number of trucks that could have gone through the toll.

The toll on a bridge is $ 1.00 for cars and $ 2.50 for trucks. In one hour, a toll operator raises a total of $ 105 in tolls. Therefore, the equation representing the relationship between c and L would be

c + 2.5L = 105

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
