Answer:
D
Explanation:
To calculate the percentage decrease in price, we need to find the difference between the original price and the reduced price, divide that difference by the original price, and then multiply by 100 to express it as a percentage.
The original price of the iPhone was $320, and it was reduced to $224. Therefore, the difference between the two prices is:
$320 - $224 = $96
To find the percentage decrease, we divide this difference by the original price:
$96 ÷ $320 = 0.3
Finally, we multiply this result by 100 to express it as a percentage:
0.3 × 100 = 30%
Therefore, the answer is D. The price of the iPhone was reduced by 30%.
