kyianna wants to buy a shirt that costs $40. If sales tax is 9.5% what is her total?

$40 * 0.095 = $3.80

$40 + 3.80 = $43.80

To find the total cost, you need to calculate the sales tax and add it to the original price of the shirt.

Step 1: Calculate the sales tax.
Sales tax is calculated as a percentage of the original price. In this case, the sales tax is 9.5% of $40. To find the sales tax amount, multiply $40 by 9.5% (or 0.095).

Sales Tax = $40 x 0.095 = $3.80

Step 2: Add the sales tax to the original price.
To find the total cost, add the sales tax amount to the original price of the shirt.

Total Cost = $40 + $3.80 = $43.80

So, Kyianna's total cost for the shirt, including sales tax, is $43.80.
