Read the passage. From “Letter from Birmingham City Jail” I must close now. But before closing I am impelled to mention one other point in your statement that troubled me profoundly. You warmly commended the Birmingham police force for keeping “order” and “preventing violence.” I don’t believe you would have so warmly commended the police force if you had seen its angry violent dogs literally biting six unarmed, nonviolent Negroes. I don’t believe you would so quickly commend the policemen if you would observe their ugly and inhuman treatment of Negroes here in the city jail; if you would watch them push and curse old Negro women and young Negro girls; if you would see them slap and kick old Negro men and young Negro boys; if you will observe them, as they did on two occasions, refuse to give us food because we wanted to sing our grace together. I’m sorry that I can’t join you in your praise for the police department.
What is the main idea of the passage?

The protesters deserve the violent treatment.

The police treat the protesters violently.

The police deserve praise for their behavior.

The protesters treat the police disrespectfully.

the police treat the protesters violently

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
