Answering this problem just necessitates some simple algebra. If we believe the expense of celery = x, then the cost of onions = 2x, and value on the carrots is 4x, this sort of that the overall expense of all vegetables = x + 2x + 4x = 7x = 21 dollars. Consequently, x = 3 bucks. visit this site right here Hence, the onions Charge six dollars.
