Valerie uses 12 fluid oz of detergent each week for her laundry. If there are 75 fluid oz of detergent in the bottle, in how many weeks will she need to buy a new bottle of detergent? Explain how you know.

She will buy new bottles after 6 weeks.

Step-by-step explanation:

Valerie required 12 oz per week for her laundry

He have total 75 oz in a bottle.

Lets take she will buy new bottle after x weeks.

Fluid required for 1 week = 12 oz/week

Fluid required for x week = 12 x oz/week

Given that total she have 75 oz

So now by equating

12 x = 75

x=6.25 weeks

It means that she will buy new bottles after 6 weeks.
