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?

How many servings are in a 60-capsule bottle of vitamin D3? ** If each serving size is 2 capsules, a 60-capsule bottle of vitamin D3 would contain 60/2=<<60/2=30>>30 servings.
How many bottles would Barry need to buy to have enough servings to last for 180 days? ** Using 30-serving bottles, to last 180 days, it would take 180/30=<<180/30=6>>6 bottles of vitamin D3.
