Thank you
Yes. B is right.
To find the percent of change, you need to calculate the difference between the new price and the original price, divide it by the original price, and then multiply by 100.
In this case, the original price is $40.00 and the new price is $44.00.
Step 1: Find the difference:
$44.00 - $40.00 = $4.00
Step 2: Divide the difference by the original price:
$4.00 / $40.00 = 0.1
Step 3: Multiply by 100 to get the percentage:
0.1 * 100 = 10%
Therefore, the correct answer is B. The percent of change when the price of the radio changes from $40.00 to $44.00 is 10%.
