Answer:
$6.49 or, rounded to the nearest tenth, $6.50.
Explanation:
First, find out how much 50% of 12.99 is:
12.99x0.5=6.495
Round 6.495 to the nearest hundredth- 6.50
Then, subtract the amount off from the original price:
12.99-6.50=6.49
So the cost of the hat after the discount is $6.49.
Hope this helps!
