Answer: The required equation is,
x = 44 - y
Explanation:
Since, x represents the number of glasses of iced tea and y represents the number of glasses of lemonade served by Fiona,
Thus, the total serving cups = x + y
According to the question,
Total serving cups = 44,
⇒ x + y = 44
⇒ x = 44 - y
Hence, the equation that represents the number of glasses of iced tea she can serve is,
x = 44 - y
