Answer:
the answer is (C) 6.250%
Step-by-step explanation:
To find the overall percentage increase in prices at the supermarket, you can use the following steps:
First, calculate the effective price increase after the government raised prices by 25%.
Let's say the original price of an item was $100.
After the government raised prices by 25%, the new price became:
New Price = Original Price + (25% of Original Price)
New Price = $100 + (0.25 * $100)
New Price = $100 + $25
New Price = $125
Now, calculate the final price after the supermarket applied a 15% discount to this new price.
Final Price = New Price - (15% of New Price)
Final Price = $125 - (0.15 * $125)
Final Price = $125 - $18.75
Final Price = $106.25
Calculate the overall percentage increase in prices compared to the original price.
Percentage Increase = [(Final Price - Original Price) / Original Price] * 100%
Percentage Increase = [($106.25 - $100) / $100] * 100%
Percentage Increase = ($6.25 / $100) * 100%
Percentage Increase = 6.25%
So, the overall percentage increase in prices at this supermarket was 6.25%.
Therefore, the answer is (C) 6.250%.
