How can a hoax to create social change?

The correct answer is A) by drawing attention to an issue that people might not know about otherwise.

A hoax helps to create social change by drawing attention to an issue that people might not know about otherwise.

A hoax is something false that people fabricated to deceive the truth behind the hoax. It is said that one lie told more than a hundred times becomes the truth. So there are people that like to manipulate the reality. And the average citizen does not like to be informed so they believe what the hear. That is when people start to pay attention to issues never before heard,

The other options of the question were B) by giving people necessary information about what they can do to help, C) by making people upset about being fooled, and D) by directly changing laws the hoaxer feels are unfair and illegal.

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

a.) it provides a clue to solve the mystery.
