Which is the best example of irony?
a science fiction short story about a robot dog with a human heart is called "fido."
b. an organization that advocates that the strong conquer the weak is called "the society of justice."
c. a high school chess club that has an elite reputation nationwide is called "bright youth."
d. a politician titles his speech about homelessness in america, "unacceptable norms."

The best example of irony here is (B) An organization that advocates that the strong conquer the weark is called "The Society of Justice".

This is ironic because justice implies equal rights for all. Instead, the committee advocates that the strong conquer the weak.

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

may i see the passage?
