Atv that usually sells for $173.67 is on sale for 15% off. if sales tax on the tv is 8%, what is the price of the tv, including tax?
a. $211.53
b. $160.91
c. $159.43
d. $157.95

173.67 discounted 15%
173.67 * (1.00 - 0.15) = 147.62

147.62 with 8% tax
147.62 * (1.00 + 0.08) = 159.43

The answer is C

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
