Sold$420 large

How many large size drinks were sold last month

Answer 1

If I'm reading your question correctly, you made $420 off large drinks. So, you just divide 420 by 3, or the total amount made by the cost of one drink.

420 / 3 = 140

You sold 140 large drinks.

Answer 2

1 large/$3 x $420 = 140 large drinks.
