In these lines from Act V of The Tragedy of Macbeth by William Shakespeare,

MACBETH. Cure her of that.
Canst thou not minister to a mind diseased,
Pluck from the memory a rooted sorrow,
Raze out the written troubles of the brain,
And with some sweet oblivious antidote
Cleanse the stuffed bosom of that perilous stuff
Which weighs upon the heart?

what emotion does Macbeth express toward the doctor?
A) anger B) fear C) sadness D) indifference

C. Sadness

Explanation:

In this dialogue, Macbeth asks the Doctor in despair if he has any antidote for a mind laden with guilt and sorrow which is the cause of a person's pain not some physical ailment.

This understanding that some mental grief is cause of a physical decay which the doctor will be unable to help him for is evident to Macbeth. Hence the emotion expressed is of sadness and helplessness.

It is obvious that such antidote to cleanse one's mind of sorrows does not exist and Macbeth's insistence on asking for it shows his sadness.

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
