### Instruction: 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? Let's write a Python program.### Response: # define the number of days and the serving size
days = 180
serving_size = 2

# calculate the total number of capsules needed
total_capsules_needed = days * serving_size

# define the number of capsules in a bottle
bottle_size = 60

# calculate the number of bottles needed
bottles_needed = total_capsules_needed / bottle_size

# since bottles cannot be sold in fractions, round up to the nearest whole number
import math
bottles_needed = math.ceil(bottles_needed)

# print the result
print(bottles_needed)
