Sharon bought a shirt for 25.99, and a skirt for 31.50 and a pair of sandal for 12.98 what would be her total cost after tax if the tax was 8%? (.08)

Add all the amounts up to get the first total

Tax is 8% of first total
8% is 8/100 and of is x so it is just 8/100 x first total

Add the tax to your first total and that is the cost.

add the numbers together to find the total price
25.99
31.50
+12.98
$70.47

Then you multiply that number by 1.08 to get the price after tax which gives you $76.11
