Answer:
550 + 3x > 1000, where x > 150
The quantities true for x are: x must be greater than 150
Step-by-step explanation:
The question claims he wants to earn OVER 1,000 that month. He already makes $550 and $3 PER PLANT he sells. Subtract $550 from $1000 and you would get 450. Then divide by 3. That makes 150 plants. So now we know the x needs to be GREATER THAN 150 plants to make over 1,000. The x would also go next to the 3 because the 3 represents how much per plant sold, and the 150 represents how many plants. The equation would be $550 + 3x > 1000, where x > 150.
