Read the passage. (1) Universal health care should be adopted by every country around the world. (2) Over 100 million people become poor every year because of healthcare bills. (3) Imagine how it feels to be afraid to go to the doctor for fear of plunging into debt. (4) That is a really terrible thing, and governments need to act. (5) The World Health Organization (WHO) says that universal health care is achievable, even in poor countries. (6) The WHO recommends spreading the costs of health care across the population, so no one is overly burdened. (7) If a responsible organization like the WHO says it is possible, then worldwide governments should implement universal healthcare immediately. Which revision is the best way to strengthen the argument? A sentence stating the claim should be added before sentence 1. Sentence 2 should be deleted because it does not clearly support the claim. Sentence 4 should be revised to incorporate strong supporting evidence. A sentence that includes a strong rebuttal should be added after sentence 7.

Sentence 4 should be revised to incorporate strong supporting evidence.

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
