Question 1025947
i solved this as follows.


let p = the original price of the shirt.


then p-2 = the sale price.


the tax would therefore be .04 * (p-2).


the total cost is therefore (p-2) + .04 * (p-2).


if this has to be less than 20, then you get:


(p-2) + .04 * (p-2) < 20


simplify this to get p - 2 + .04 * p - .04 * 2 < 20


simplify further to get p - 2 + .04 * p - .08 < 20


combine like terms to get 1.04 * p - 2.08 < 20


solve for p to get p < (20 + 2.08) / 1.04


this results in p < 21.23076923.


i tested this out and it makes sense.


looking at the selections, however, i can't make heads or tails out of any of them.


any value of p less than 21.23076923 will satisfy the inequality.


p, however, would have to be greater than or equal to 2, otherwise the sale price would be negative.


i did a search on the internet for the question and this is what i came up with.

this came from the following link.

i calculated the solution to be selection b in this test.
