Ratio is the comparison of sizes of two quantities of the same unit. Proportions are the equality of two ratios. A/b =c/d
We are given the equation:
DA - 2qA = B³
Taking 'A' common on the LHS
A(D - 2q) = B³
Dividing both sides by (D - 2q)
A = B³ / (D - 2q)
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
