Answer:
8x+8y
Step-by-step explanation:
y + 3x + 4y + 2x + 3y +3x
<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>
3x+2x+3x
And the y with y
y+4y+3y
Which is;
3x+2x+3x+y+4y+3y
8x+8y
Answer: the only answer is d
Step-by-step explanation:
"on sale for 12% off" means that whatever the price is (y) we multiply it by 0.88 since 1-0.12 = 0.88
Price before discount = original price = y
Price after discount = 0.88y
Put another way, we took 88% of the original price to get the discount price.
------------------------------------
Now tack on the sales tax. We do this by multiplying the discount price by 1.03 (1 + 0.03 = 1.03)
So we have:
final cost = 1.03*(discount price)
final cost = 1.03*(0.88y)
final cost = 0.9064y
telling us that the final cost is 90.64% of the original price (y). With the tax added, the discount is not 12% but actually 100% - 90.64% = 9.36%
