Calculating the Amount of Hay Required

To calculate the amount of hay required for 18 cows for 25 days, we can use the given information for 20 cows for 15 days and apply it to the new scenario.

Given: - 20 cows require 3.6 tons of hay for 15 days

We can calculate the amount of hay required for 18 cows for 25 days using the following steps:

1. First, we need to find the daily hay consumption per cow: - Daily hay consumption per cow = Total hay consumption / (Number of cows * Number of days) - Daily hay consumption per cow = 3.6 tons / (20 cows * 15 days)

2. Then, we can use the daily hay consumption per cow to find the total hay required for 18 cows for 25 days: - Total hay required = Daily hay consumption per cow * (18 cows * 25 days)

Let's calculate the amount of hay required for 18 cows for 25 days using the above steps.

Calculation

1. Daily hay consumption per cow: - Daily hay consumption per cow = 3.6 tons / (20 cows * 15 days) - Daily hay consumption per cow = 3.6 tons / 300 cow-days - Daily hay consumption per cow = 0.012 tons/cow-day

2. Total hay required for 18 cows for 25 days: - Total hay required = 0.012 tons/cow-day * (18 cows * 25 days) - Total hay required = 0.012 tons/cow-day * 450 cow-days - Total hay required = 5.4 tons

Therefore, the amount of hay required for 18 cows for 25 days is 5.4 tons.
