Answer 1

16.15 ml of Grow-it-right plant food must be mixed with 1 gallons of water.

Explanation:

It is recommended that 8.5 ml of Grow-it-right plant food be mixed with 2 L of water for feeding house plants.

So, 2 liters of water is mixed with 8.5 ml of Grow-it-right plant food.

Then, 3.8 liters of water should be mixed with
`(8.5)/(2) * 3.8 = 16.15` ml of Grow-it-right plant food.

Now, since 1 gallon is equivalent to 3.8 liters, therefore, 16.15 ml of Grow-it-right plant food must be mixed with 1 gallon of water. (Answer)
