Answer:
The answer is D, or 525.
Explanation:
If each bag costs 250 with 5% tax, then the tax amount is 12.5. To find this, divide 5% by 100 to get a decimal of 0.05. Then, multiply 250 by 0.05 to find 5% of 250, which is 12.5. Add the cost of the bag with the tax to get a total cost per bag of 262.50. Then, multiply this number by 2 because the girls purchased two bags to get a total cost of 525 dollars.
