Question
A greenhouse owner purchases fertilizer in 60-gallon drums. The fertilizer is mixed with water to make several batches of solution. Each batch of solution is made by mixing 3 quarts of fertilizer with water. What is the maximum number of batches of solution that can be made from one 60 -gallon drum of fertilizer? (1 gallon = 4 quarts)
- 40
- 60
- 80
- 180
The correct answer is: 80
HINT: Find the total number of quarts of fertilizers, then find the number of batches of solution.
Complete step by step solution:
Total fertilizer purchased by green house owner = 60 gallon
It is given that 1 gallon = 4 quarts
Here we have 60 gallons. So, 60 × 4 = 240 quarts.
Given that each batch of solution is made by mixing 3 quarts of fertilizer with water.
Number of batches of solution made from 60 gallon (240 quarts) drum of fertilizer = = 80.
80 batches of solution can be made from one 60 gallon drum of fertilizer.
Hence option C is the correct answer.
Note: Given that 1 gallon is 4 quarts. Since we have 60 gallons, we have 240 quarts of fertilizers.
To make 1 batch of solution we need 3 quarts. Let the number of batches that can be made from 240 quarts be
x. So we get . On simplification, we get x = 80
