Final answer:
To determine the best sale for purchasing 2 new pairs of prescription glasses, Mr. Garcia needs to compare the total costs under different deals and select the one offering the greatest savings through the highest percentage discount or the largest fixed dollar reduction.
Step-by-step explanation:
Mr. Garcia is looking at purchasing 2 new pairs of prescription eyeglasses, each retailing for $95. To identify which sale is the best deal, we need to compare the total costs under the different sale conditions. Clearly, we should look for the option that offers the greatest savings.
Calculations of sales deals might involve a percentage discount, a reduction by a fixed dollar amount, or a special offer such as 'buy one, get one free'. For example, a 20% off sale would save Mr. Garcia 20/100 * $95 * 2 = $38, making the cost of two pairs $152. A 'buy one, get one half off' deal would save him $47.50, and he would pay $142.50 for both pairs. The fixed dollar amount would depend on the exact offer, but it must beat the $142.50 to be considered the best deal.
Without specific deals to compare, the best general advice would be to go for the highest percentage off or the largest fixed amount reduction when purchasing multiple items like glasses. Mr. Garcia should also consider the quality of the glasses and any additional benefits that might come with the more expensive options before making his decision.
Using these comparisons in buying decisions helps ensure that one gets the greatest value for their money.
