The correct answer is D, -5 1/3.
The reason is that on a number line -3 1/4 would be placed to the right of -5 1/3.
The further you are to the right on the number line, the bigger the number.
As you know 30/45 = 6/9
So a = 9 makes the equation true
17/21 you just have to find the highest common factor, which in this case, is two
Take 10% of the snowboard price.
10% = 0.1
109 * 0.1 = $10.90 (10% discount)
109 - 10.9 = $98.10 (Price with discount).
Take 12% of the new snowboard price.
12% = 0.12
98.1 * 0.12 = 11.772 (Round to 11.77)
98.10 - 11.77 = $86.33 (Final discounted price)
Take 6% tax on the new snowboard price.
6% = 0.06
86.33 * 0.06 = 5.1798 (Round to 5.18)
86.33 + 5.18 = $91.51
