Final answer:
To determine the best deal for rollerblades, one must calculate the final cost including the sale discount and tax at Roller World and the cost with tax at Outdoor Adventures. The final cost is $84.69 at Roller World and $86.39 at Outdoor Adventures; thus, Roller World offers the better deal.
Step-by-step explanation:
The student's question involves determining which store offers a better deal for a pair of rollerblades once the sale discount and sales tax are applied. To answer this question, we need to calculate the final cost at both stores including the sales tax.
At Roller World, with a regular price of $94 and a 15% discount, we first calculate the discount amount: $94 * 15% = $14.10. The sale price of the rollerblades before tax at Roller World would then be $94 - $14.10 = $79.90.
To include the 6% sales tax, we then calculate $79.90 * 6% = $4.794, which we can round to $4.79. Adding this tax to the sale price gives a final cost of $79.90 + $4.79 = $84.69 at Roller World.
At Outdoor Adventures, the price is $81.50 with no discount. Calculating the 6% sales tax gives $81.50 * 6% = $4.89. Adding this to the original price, the final cost at Outdoor Adventures is $81.50 + $4.89 = $86.39.
Comparing the two final costs, $84.69 at Roller World and $86.39 at Outdoor Adventures, we can see that the better deal for Ramundo is at Roller World.
