Final answer:
Shree received approximately a 29.75% discount on the speaker, calculated by taking the discount amount of $180 (the difference between the retail price of $605 and the purchase price of $425) and dividing it by the retail price, then multiplying by 100.
Step-by-step explanation:
The question asks us to calculate the percentage of discount Shree received on a new speaker for his DJ Booth that normally retails for $605 and was purchased for $425.
To find the discount percentage, we first need to calculate the discount amount, which is the difference between the retail price and the purchase price. The discount amount is:
$605 - $425 = $180
Next, we calculate the discount percentage by dividing the discount amount by the original retail price and then multiplying by 100 to get a percentage:
(( $180 ÷ $605 ) × 100) % ≈ 29.75%
Thus, Shree received a discount of approximately 29.75% on the speaker.
