Answer:
[tex]\$843.67[/tex]
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 [tex]\implies896\cdot 0.88=\$788.48[/tex]
Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.
Final price [tex]\implies 788.48\cdot 1.07\approx \boxed{\$843.67}[/tex]
