What is the supporting idea of the third section:
"How Important Are the Elements of a Fair Trial?"
CENTRAL IDEA:
In the United States, the right to a fair trial is an important civil liberty that
has several elements that protect citizens.
To understand the importance of a fair trial in the United
States, a person should know what trials are like in other
countries.
China's legal system has made great improvements, but it is
still very different from that of the United States.
There is no set number of people that a jury must have to
guarantee a person a fair trial.
In places like North Korea, people accused of a crime might
have to wait a long time for a trial.

in the problem you wrote said that the taxi charges $0.070 per mile(which would be 7 cents per mile), but then in your suggested equation you have it as $0.70 per mile (which is 70 cents per mile).

the latter seems more realistic, so i will assume that the taxi costs $5.00 and charges $0.70 per mile with tolls costing an additional $3.50. and it asks you to find how far you can travel on $36.50.

let x the number of miles traveled. since the taxi charges $0.70 per mile, multiplying this by the miles traveled (x) will yield the cost of the taxi ride as far as how far it took you. then adding this amount to the cost of the taxi ($5.00) and the additional cost for the tolls ($3.50) will give you the total cost of the taxi ride ($36.50)

that is,

            (0.70)x + 5.00 + 3.50 = 36.50

adding the like terms on the left-hand side of this equation, we arrive at the following:

            (0.70)x + 8.50 = 36.50

subtracting 8.50 from both sides of the equation, we get:

            (0.70)x = 28.00

to solve for x, divide both sides of the equation above by the coefficient of x (that being, 0.70):

            x = 40

thus, you can travel up to 40 miles on $36.50
