What is the total cost of your items, including tax

total cost: 21.52
tax: 6%

The total cost of the items including tax would be $22.84.

To calculate the total cost, you need to add the tax amount to the original cost. Here's how you can do it step-by-step:

Step 1: Calculate the tax amount by multiplying the total cost by the tax rate (6% or 0.06):
Tax amount = total cost * tax rate
Tax amount = 21.52 * 0.06
Tax amount = 1.2912

Step 2: Add the tax amount to the total cost to get the final total cost:
Final total cost = total cost + tax amount
Final total cost = 21.52 + 1.2912
Final total cost = 22.8112

Therefore, the total cost of the items, including tax, is $22.81.

To calculate the total cost of the items, including tax, you need to multiply the total cost by the tax rate and then add the result to the total cost.

Let's break it down:

1. Convert the tax rate from a percentage to a decimal by dividing it by 100. In this case, the tax rate is 6%, so it would be 6/100 = 0.06.

2. Multiply the total cost by the tax rate. In this case, the total cost is $21.52, so you would calculate: $21.52 * 0.06 = $1.2912.

3. Add the result from step 2 to the total cost. $21.52 + $1.2912 = $22.8112.

The total cost of the items, including tax, is $22.8112.
