Final answer:
To determine the final cost after a 10% discount on an $8.60 item, calculate the discount amount ($0.86) and subtract it from the original price to find that Paul will pay $7.74.
Step-by-step explanation:
To calculate how much Paul will pay with a 10% discount on an $8.60 purchase, we first need to determine the amount of the discount. To find this, we convert the percentage into a decimal by dividing by 100, which makes 10% become 0.10. We then multiply the original price by this decimal to find the discount amount.Discount amount = Original price × Discount decimal Discount amount = $8.60 × 0.10Discount amount = $0.86Next, we subtract the discount from the original price to get the final cost.Final cost = Original price - Discount amount Final cost = $8.60 - $0.86Final cost = $7.74In conclusion, Paul will pay $7.74 for his purchase after a 10% discount is applied.
