<span>4x-y = 15 3x+2y = -8 Multiplying the first equation by two makes for an easy elimination of the y variable. 8x - 2y = 30 3x + 2y = -8 Add vertically. 11x = 22. Divide by 11 on both sides and get x = 2. Plug into an equation. 4(2) - y = 15 8 - y = 15 8 = 15 + y 8 - 15 = y -7 = y. Thus the solution is indeed (2, -7).</span>

$ 27.09

Step-by-step explanation:

So, the amount of marked off = 16% of regular price

= 16% of 32.25

Hence, the the price of the watch during the sale = Regular price - marked off

= $ 32.25 - $ 5.16

= $ 27.09

Last option is correct.
