Answer 1

Well, one bottle would be $7, two bottles $14, three bottles $21. Try taking $5 off the total of one of those numbers so you don't exceed $16.

Answer 3

Each bottle is 7 dollars. Normally, you could only buy 2, because that would equal 14. But, since you have a coupon, you could buy 3 for 21 dollars, then take 5 off the total. You would need exactly your amount: 16 dollars. Get it?
