Kyle wants to buy a new laptop that has an original price of $\$ 540$. The store is having a sale, so the laptop is 10 percent off, which amounts to a discount of $\$ 54$. If sales tax is 8 percent on the final price of the laptop, how much tax will he need to pay? $\$ 38.88$ $\$ 43.20$ $\$ 47.52$ $\$ 48.60$

Step 1 ：First, we need to calculate the discounted price of the laptop. This can be done by subtracting the discount from the original price. So, the discounted price is \(540 - 54 = 486\) dollars.

Step 2 ：Then, we need to calculate the sales tax on the discounted price. This can be done by multiplying the discounted price by the sales tax rate. So, the sales tax is \(486 * 0.08 = 38.88\) dollars.

Step 3 ：Final Answer: The sales tax Kyle will need to pay is \(\boxed{38.88}\) dollars.
