For questions 1 and 2, use the following information about toll cost for trucks.

Truck (2 or 3 axles) : $3.00

Truck (4 or 5 axles) : $6.25

Truck (6 or more axles) : $10.00

One morning, 3 trucks, each with 5 axles, and 1 truck with 8 axles, crossed the bridge in one direction.

Write an expression to show the total amount of toll money collected from those 4 trucks that morning. Then evaluate the expression. Show your work. How much toll money was collected from those 4 trucks that morning?

Later in the day, the 3 trucks with 5 axles and the truck with 8 axles returned to cross the bridge in the opposite direction. Show how you can modify the expression you wrote in Part (a) so that it represents the total amount of toll money collected from those 4 trucks that day. Then evaluate the expression. Show your work. How much toll money was brought in from those 4 trucks that day?

Jaylen Bartlett · Answer 1

What we know:

Truck (2 or 3 axles) : $3.00

Truck (4 or 5 axles) : $6.25

Truck (6 or more axles) : $10.00

Day1 = 3 trucks with 5 axles and 1 truck with 8 axles passed the bridge

What we need to find:

Part a: an expression that represents the first passing of the 4 trucks and

a solution to the the first expression

Part b: a modification of first expression that includes the return passing of the 4 trucks and a solution for the trucks passing both times.

Part a:

3 (6.25) + 1 (10.00)

3 (6.25) + 1 (10.00) = $28.75

Part b:

2[3 (6.25) + 1 (10.00) ]

2[3 (6.25) + 1 (10.00) ]=2[28.75]=$57.50
