Lizzy: The doctor told Barry to take vitamin D3 for 180 days to help protect him from infections. The pharmacy only sold vitamin D3 in bottles containing 60 capsules, with a daily serving size of 2 capsules. How many bottles would Barry need to buy to have enough servings to last for 180 days?.
Me: Hmmm, let me think. I think this is the detailed solution:
If each serving size is 2 capsules, a 60 - capsule bottle of vitamin D3 would contain 60 / 2 = 30 servings. Using 30 - serving bottles, to last 180 days, it would take 180 / 30 = 6 bottles of vitamin D3. Final answer: 6.
