Answer 1

a) m x 3 ≥ 2,400 is the formed inequality.

b) The farmer should sell at least 800 bushels to earn an amount of $2,400

Explanation:

Here, the cost of each bushel = $3

The least money the farmer wants to earn = $2400

Let m be the number of bushels the farmer sells.

So, according to the question:

The money earned after selling m bushels at $3 each ≥ $2,400

or, m x ($3) ≥ $2,400

⇒
`m \geq (2,400)/(3)  = 800`

or, m ≥ 800

Hence, the farmer should at least 800 bushels to earn an amount of $2,400
