Answer:
The answer is $24.09.
Explanation:
Leo spent $23.61 on groceries and the tax was $0.48, so the total was $23.61 + $0.48 = $24.09.
The other options are incorrect. Option A is the subtotal before tax, option B is the subtotal minus tax, option C is the subtotal minus $0.13, and option D is the subtotal plus $0.13.
Therefore, the total cost of Leo's groceries was $24.09.
