A farmer 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
1 answer:
Answer:
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

Answer:
For 124 chirps per minute the temperature is 68 ºF.
For 68 chirps per minute the temperature is 54 ºF.
Step-by-step explanation:
Linear functions are those whose graph is a straight line. A linear function has the following form
b is the constant term or the y intercept. It is the value of the dependent variable when x = 0.
m is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.
We know that
- At 104 chirps per minute, the temperature is 63 ºF.
- At 176 chirps per minute, the temperature is 81 ºF.
This information can be converted to Cartesian coordinates (x, y). Where x = the number of chirps per minute and y = the temperature in ºF.
To find a linear function that let us find the outside temperature from how fast crickets chirp we must:
- Find the slope:
- Find the equation:
Solving for b
Therefore, the linear function is
Now, using this linear function we can know the temperature when we know the chirps per minute:
For 124 chirps per minute the temperature is:
For 68 chirps per minute the temperature is:
