Eduardo is taking an essay test. He reads the question, organizes his thoughts, and begins to write. After he completes his essay, Eduardo looks and sees he has time to spare. He looks back through his essay and has written everything he wanted to write. What should Eduardo do next?
A)Look at each paragraph to see where more can be added
B)Nothing. If his essay is complete, he should not write more
C)Turn to his neighbor to see if he or she needs any help
D)Write one more paragraph about an additional thought he has

A

Explanation:

Cause your always have to go back and see where more can be added  so u can more credit for answering the question

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
