Step-by-step explanation:
In economics, formula for total revenue is;
Total revenue = quantity sold × price.
In this question;
Let he quantity of drinks sold be x
We are told that the selling price is $3.50 per drinks
Since quantity is "x", then total revenue can be said to be R(x)
Thus;
Total revenue; R(x) = x × 3.50
R(x) = 3.5x
