Final answer:
The inequality in standard form that describes the situation is 9x + 5y ≤ 284.
Step-by-step explanation:
To represent the situation of Steve selling cups of lemonade, we can write the inequality in standard form.
Let x represent the number of regular cups of lemonade and y represent the number of small cups of lemonade.
The total number of ounces of lemonade can be found by multiplying the number of regular cups (x) by 9 and the number of small cups (y) by 5.
Therefore, the inequality in standard form is 9x + 5y ≤ 284.
