Apharmacist is trying to stock the pharmacy with cheaper alternatives for customers. she will stop carrying the more expensive items. in doing so, she is trying to determine which of the following forms is the most expensive. tablet form comes in 50 mg tablets and cost $75.00 for a bottle of 100 tablets. capsule form comes in 75 mg capsules and cost $63.75 for a bottle of 85 capsules caplet form comes in 100 mg caplets and cost $70.00 for 40 caplets.

For the first case we know that 100 tablets of 50 mg each costs $75
So cost of 1 tablet = 75/100 dollar
                             = 0.75 dollar
Now cost of 1 mg in this case is = 0.75/50 dollar
                                                     = .015 dollar
For the second case we know that 85 capsules of 75 mg each costs $63.75
So cost of 1 capsule = 63.75/85 dollars
                               = 0.75 dollar
Now cost of 1 mg of capsule in this case = 0.75/75 dollars
                                                                   = 0.010 dollars
For the third case we know that 40 caplets of 100 mg each cost $70
So cost of 1 caplet = 70/40 dollar
                                = 1.75 dollar
Now cost of 1 mg of caplet in this case = 1.75/100 dollars
                                                               = .017 dollars
So the costliest among all the medicines are the caplets.
