Answer 1

a sink that holds 10 gallons , 2 Liters of water.

I need to add a solution at a rate of 2.5 oz for every four gallons of water.

How many oz of solution do I need for the amount of water in the sink.

This problem involves unit conversions and rates.

The amount the sink holds is given in gallons and liters. Since the rate of the solution is given in oz and gallons. We should convert the amount the sink holds into gallons.

The relationship for liters and gallons is 1 gallon = 3.785 liters. 1 liter = 0.264 gallons

So the sink holds 10 gallons + 2(0.264) gallons of water. = 10.528 gallons.

Now to determine how much of the solution needed we will multiply by the rate (2.5 oz / 4 gallon)

10.528 gallons x (2.5 oz / 4 gallon)

= 6.58 oz needed.
