A 12 ounce bottle of shampoo last enrique 16 weeks. how lonh would you expect an 18 ounce bottle of the same brand to last him?

For Enrique a 12 ounce bottle lasts for 16 weeks. This is a known fact. We need to find the amount of days or weeks an 18 ounce bottle of the same brand of shampoo last.

Now

12 ounce bottle lasts = 16 weeks

= (16 * 7) days

= 112 days

18 ounce bottle lasts = (112/12) * 18

= 168 days

= 168/7 weeks

= 24 weeks

So 18 ounce of the same brand of shampoo will last for 24 weeks.
