Read the excerpt from "code talkers.”

the use of navajo code was so successful that its existence was kept secret until 1968 so that the marines could continue to use it, if necessary. two decades later, many of the code talkers were recognized for their service. in 1982, president ronald reagan declared august 14 navajo code talkers day, and in 2000 president bill clinton awarded the congressional medal to the first twenty-nine code talkers. in the years since, code talkers from the navajo and thirty-two other american indian tribes have been awarded the medal.

the author’s purpose in this paragraph was to

a. entertain readers with a story about how code talkers received medals for their service during wartime.

b. inform readers that the code talkers were recognized by the us government for their critical work during wartime.

c. educate readers about the history of us presidents and holidays created to honor groups like the code talkers.

d. persuade readers that they should learn to create code so they can be recognized by the us government.

B. inform readers that the code talkers were recognized by the US government for their critical work during wartime.

In this excerpt, the author's main objective was to inform readers of the fact that the code talkers were recognized by the US government for their critical work during wartime. He does this by telling the reader how successful this method was, and how Marines continued to rely on it for decades. Moreover, it states that many Navajo code talkers were recognized for their service, given medals, and that a special holiday was declared in their honour.

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
