Afarmer wants to sell enough grain to get at least $2,400. if the selling price is $3 per bushel, how many bushels must he sell?

write an inequality and solve.



and show

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

Step-by-step 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

⇒

or, m ≥ 800

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