When i refer to integrity, i have something very specific in mind. integrity, as i will use the term, requires three steps: discerning what is right and what is wrong; acting on what you have discerned, even at personal cost; and saying openly that you are acting on your understanding of right and wrong. the first criterion captures the idea that integrity requires a degree of moral reflectiveness. the second brings in the ideal of a person of integrity as steadfast, a quality that includes keeping one's commitments. the third reminds us that a person of integrity can be trusted.

based on the passage above, which of the following reflects the correct use of brackets?
a) carter comments that “[a] person of integrity can be trusted[.]”
b) carter believes that “[i]ntegrity . . [r]equires [t]hree [s]teps.”
c) [carter] writes, “[i]integrity requires a degree of moral reflectiveness.”
d) carter explains, “[integrity is] a quality that includes keeping one’s commitments.”

The correct answer is D. Carter explains, “[Integrity is] a quality that includes keeping one’s commitments.”

Explanation:

Brackets are a type of punctuation mark mainly used to add information, in the case of square brackets [] these are commonly used in quotations to add words that were not specifically said by the original author but that clarify the quotation and do not change the words of the original author. This use is reflected in “[Integrity is] a quality that includes keeping one’s commitments" because in the original text the words "integrity is" do not appear in this section but other words in the quotation refer to the definition of integrity by the original author and this makes necessary for the writer quoting add "integrity is" for clarification.

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
