Final answer:
Brandon pays $3.39 in sales tax for a radio that costs $48.39, with a sales tax rate of 7%. The tax is calculated by converting the percentage to a decimal and then multiplying by the cost of the radio.
Step-by-step explanation:
The question is about calculating the sales tax that Brandon needs to pay for purchasing a radio. Since the sales tax rate is 7%, we first convert this percentage into a decimal by dividing it by 100. Therefore, 7% becomes 0.07 as a decimal. Next, we multiply this decimal by the cost of the radio to find the amount of tax he will have to pay.
To calculate the sales tax on a $48.39 purchase:
- Convert the percentage to a decimal: 0.07
- Multiply this decimal by the purchase price: $48.39 x 0.07
- Round the result to the nearest cent.
Calculating gives us:
$48.39 x 0.07 = $3.3873, which we round to $3.39. Therefore, Brandon pays $3.39 in taxes.
