Answer:
Step-by-step explanation:
Let's break the price changes down:
Initial price: $896
On sale for 12%, meaning the computer will be 100-12=88% of the original price:
New sale price 
Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.
Final price 
So if you distribute 4 in the first parentheses, you get 12x+20y+8z.
Then you distribute 3 in the second parentheses. You'll get 3x-3z. That all equals 12x+20y+8z+3x-3z.
Now you have to start combining numbers with the same variable. Start with x. 12x+3x is 15x.
y has no other common variable, it's left alone.
8z-3z is 5z
All together now with the numbers in simpler form, the equation is 15x+20y+5z
Jenna's would be the right answer because when you distribute 5 in her answer you get 15x+20y+5z
