Final answer:
Nathan pays a total of $5.70 for the apples after calculating an 8% sales tax on the original price of $5.28, which is $0.42, and adding it to the original cost.
Step-by-step explanation:
To calculate how much Nathan pays after taxes for the apples, first we need to find the amount of sales tax. Since the sales tax rate is 8%, we convert this percentage to a decimal by dividing by 100, which gives us 0.08. We then multiply the cost of the apples ($5.28) by this decimal to find the sales tax amount.
So, the sales tax Nathan has to pay is $5.28 * 0.08 = $0.4224. Since we typically round tax amounts to the nearest cent, the sales tax would be $0.42 when rounded. Finally, we add this sales tax to the original cost of the apples to find the total amount Nathan pays.
$5.28 + $0.42 = $5.70
Therefore, Nathan pays a total of $5.70 for the apples after including the sales tax.
