Answer:
One glass of iced tea cost $2.72
Step-by-step explanation:
Let,
x be the amount of gift card.
y be the amount of one glass of iced tea.
According to given statement;
Julie and her friend bought tea and remaining balance was $14.85
x - 2y = $14.85 Eqn 1
All the six members bought tea and remaining balance was $3.97
x - 6y = $3.97 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 4
Hence,
One glass of iced tea cost $2.72
