Question

Wildflower sells cell phone cases for $30 each. A customer signed up for email promotions and received a 5% discount of the price. Sales tax of 5% was applied after the discount. What was the final price of cell phone case?

Answer 1

$29.93

Step-by-step explanation

The cost of he cell phone cases is $30.

A discount of 5% would mean that 5% was deducted from the price of the cell phone case.

This means that the new price is:

`\begin{gathered} Price\text{ = 30 - (}(5)/(100)\cdot\text{ 30)} \\ \text{Price = 30 - 1.5} \\ \text{Price = \$28.50} \end{gathered}`

A sales tax of 5% was applied after this discount. This means that 5% of the new price will be added to it for tax.

Therefore, the final price of the cell phone case is:

`\begin{gathered} \text{ Final Price = 28.50 + (}(5)/(100)\cdot28.50) \\ FP\text{ = 28.50 + \$1.43} \\ FP\text{ = \$29.93} \end{gathered}`

That is the final price of the cell phone case.
