<span>(6y3 + 17y − 3) − (4y3 − 11y + 9)
</span>= 6y3 + 17y − 3 − 4y3 + 11y - 9
= 2y3 + 28y - 12
That would be a total of 32

Answer:
B. x=y
Step-by-step explanation:
A 5% tax charge is equivalent to multiply the current price by 1.05. On the other hand, a 5% discount is equivalent to substrace the current the 5% of it, so in the end, you multiply the current price by 0.95.
For X we should multiply first by 0.95, then by 1.05
For Y we multiply first by 1.05, then by 0.95
Hence, if L = price list, we have
- x = L*0.95*1.05 = 0.9975L
- y = L*1.05*0.95 = 0.9975L
- z = L
As a result, x=y<z. Option B is correct.
Note that applying discount first or charging taxes first doesnt matter because the order of the factors doesnt ater the product.
