Pls I need help I ve doing 2 hours and 25 mins and 43 seconds of ixl and I cant figure out this question I already answered 69 questions help

Mrs. Gregory runs a house cleaning business. To save money, she bought a 1-liter container of concentrated cleaner. She mixed the cleaner with 10 liters of water. To make sure it was strong enough, she used 200 milliliters to clean her kitchen. It worked well, so she filled as many 600-milliliter spray bottles as she could. How many spray bottles did she fill?

Answer:

Mrs Gregory started with 1 litre of concentrated cleaner, which is equal to 1000 millilitres of cleaner. (we have to convert litre to millilitres because " she used 200 millilitres to clean her kitchen)

She mixed the 1000 millilitres of cleaner with 10 litres of water, which is equal to 10,000 millilitres of water. This gives a total of:

1000 + 10,000 = 11,000 millilitres of cleaner solution

She used 200 millilitres of the solution to clean her kitchen, which leaves:

11,000 - 200 = 10,800 millilitres of cleaner solution

To fill the 600-millilitre spray bottles, she needs to divide the total amount of cleaner solution by the amount of solution in each bottle:

10,800 / 600 = 18

Therefore, Mrs Gregory filled 18 spray bottles.
