A lawn treatment recommends using its product at a rate of 6 ml concentrate per 5 liters of water to cover an area of 60 square meters. A 5-gallon sprayer is being used for the mixture. How many milliliters of concentrate should be used in the 5-gallon sprayer if 1 gallon is approximately 3.785 liters? Round your answer to the nearest hundredth, if necessary.

To determine the number of milliliters of concentrate to use, we need to convert the volume of the 5-gallon sprayer from gallons to liters and set up a proportion with the given rate of concentrate. Solving for x, we find that approximately 22.74 ml of concentrate should be used in the 5-gallon sprayer.

Explanation:

To calculate the number of milliliters of concentrate to be used in the 5-gallon sprayer, we need to convert the volume of the sprayer from gallons to liters. Since 1 gallon is approximately 3.785 liters, then 5 gallons is approximately 18.925 liters.

Next, we can set up a proportion using the given rate of 6 ml concentrate per 5 liters of water.

Let's set up the proportion:

6 ml / 5 liters = x ml / 18.925 liters

Cross multiplying, we get:

5x = 6 * 18.925

Solving for x, we get:

x = (6 * 18.925) / 5

Calculating this, we find that x is approximately 22.74 ml.
