Answer:First, let's calculate the total cost of the sugar: - 3 kg of sugar * 57.50 pesos/kg = 172.50 pesos Next, calculate the total cost of the rice: - 10 kg of rice * 51.50 pesos/kg = 515 pesos Now, add the cost of sugar and rice: - 172.50 pesos + 515 pesos = 687.50 pesos Now, add the cost of groceries she still needs to buy: - 687.50 pesos + 575.75 pesos = 1263.25 pesos The total cost of all groceries is 1263.25 pesos. To find out how much more she needs, subtract her bill from the total cost: - 1263.25 pesos - 1000 pesos = 263.25 pesos Therefore, she still needs 263.25 pesos to buy all the groceries.
