Final answer:
With a 30% discount on $18.00 sheets, the sale price is $12.60 per sheet. To accurately compare this to a previous offer, we need the details of that offer, which are not provided.
Step-by-step explanation:
To determine which offer is better, we first need to calculate the sale price of the sheets that are 30% off from the regular price of $18.00 per sheet. A 30% discount on an $18.00 item is calculated as:
$18.00 × 30% = $18.00 × 0.30 = $5.40
Subtracting the discount from the original price gives us the sale price:
$18.00 - $5.40 = $12.60
Therefore, the sale price per sheet with a 30% discount is $12.60. To compare, we would need the details of the previous offer, which have not been provided. Without information about the previous offer, we cannot determine which deal is better.
