Answer 1

Calculation of Remaining Feed for the Bird Farm

To calculate the amount of feed that is left after the first and second months, we need to subtract the amount of feed consumed in each month from the total amount of feed initially prepared.

Given information: - Total amount of feed prepared: 2600 tons - Feed consumed in the first month: 8.5% of 2600 tons - Feed consumed in the second month: 30 tons more than the first month

Let's calculate the amount of feed consumed in the first month: - Feed consumed in the first month = 8.5% of 2600 tons

To find the amount of feed consumed in the second month, we need to add 30 tons to the amount consumed in the first month: - Feed consumed in the second month = Feed consumed in the first month + 30 tons

To calculate the amount of feed remaining, we subtract the total feed consumed (first month + second month) from the total amount of feed prepared: - Feed remaining = Total feed prepared - (Feed consumed in the first month + Feed consumed in the second month)

Let's calculate the values:

Feed consumed in the first month: - Feed consumed in the first month = 8.5% of 2600 tons - Feed consumed in the first month = 0.085 * 2600 tons - Feed consumed in the first month = 221 tons

Feed consumed in the second month: - Feed consumed in the second month = Feed consumed in the first month + 30 tons - Feed consumed in the second month = 221 tons + 30 tons - Feed consumed in the second month = 251 tons

Feed remaining: - Feed remaining = Total feed prepared - (Feed consumed in the first month + Feed consumed in the second month) - Feed remaining = 2600 tons - (221 tons + 251 tons) - Feed remaining = 2600 tons - 472 tons - Feed remaining = 2128 tons

Therefore, there are 2128 tons of feed remaining for the bird farm.
