Answer:
B. $75.90
Explanation:
Step 1: Calculate the cost per capsule:
- Since the cost for 100 capsules is $220.00, the cost per capsule can be found by dividing the total cost by the number of capsules:
Cost per capsule = $220.00 / 100 = $2.20
Thus, it costs $2.20 per capsule.
Step 2: Calculate the markup amount:
- The markup percentage is 15%.
- Thus, we can find the markup amount by multiplying the cost per capsule by the markup percentage (note that we convert the percentage to a decimal when multiplying, so 15% becomes 0.15):
Markup amount = $2.20 * 0.15 = $0.33
Step 3: Calculate the retail cost per capsule:
- The retail cost per capsule can be found by adding the markup amount to the cost per capsule:
Retail cost per capsule = Cost per capsule + Markup amount = $2.20 + $0.33 = $2.53
Step 4: Calculate the retail cost for 30 capsules:
- To find the retail cost for 30 capsules, we multiply the retail cost per capsule by the number of capsules:
Retail cost for 30 capsules = Retail cost per capsule * 30 = $2.53 * 30 = $75.90
Therefore, the retail cost for 30 capsules would be $75.90, so the correct answer is B. $75.90.
