Julie used her gift card for the local coffee shop to buy iced teas for herself and five friends. After she and one friend place
valentina_108 [34]

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

(x-2y)-(x-6y)=14.85-3.97\\x-2y-x+6y=10.88\\4y=10.88

Dividing both sides by 4

\frac{4y}{4}=\frac{10.88}{4}\\y=2.72

Hence,

One glass of iced tea cost $2.72
