. A toll bridge charges $1.00 for passenger cars and $2.50 for other vehicles. Suppose that during daytime hours, 60% of all vehicles, on average, are passenger cars. If 1000 vehicles cross the bridge that afternoon, what is the expected toll revenue?

=$1,600

Explanation:

The charges for passenger cars are $1.0

Other vehicles are $2.60

1000 vehicles pass, 60 % are charged $1, $0% are charged $2.50.

i.e., 600 vehicles are charged $1, and 400 vehicles are charged $2.50

Total revenue will be

=(600 x 1)+(400 x 2.50)

=$600 + $1,000

=$1,600

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

now clearing the formula to solve for capital we got:

and we reach the answer investment = $14,174.20
