Question

Cost of Item
Tax Rate
  ​$400
8​%

Answer 1

To find the sales tax and the total cost, you can follow these steps:

1. Calculate the Sales Tax: \[ \text{Sales Tax} = \text{Cost of Item} \times \left(\frac{\text{Tax Rate}}{100}\right) \] Substituting the values: \[ \text{Sales Tax} = 400 \times \left(\frac{8}{100}\right) = 400 \times 0.08 = 32 \]

2. Calculate the Total Cost: \[ \text{Total Cost} = \text{Cost of Item} + \text{Sales Tax} \] Substituting the values: \[ \text{Total Cost} = 400 + 32 = 432 \]

So, the amount of the sales tax is $32, and the total cost is $432.
