43%

Rationale: If a prescription drug costs $35.00 and retails for $50.00, the percentage of markup is 43%. This is calculated by subtracting $35.00 from $50.00, which leaves $15.00 . This is the markup amount, so divide it by the drug's cost. $15.00 divided by $35.00 = 0.428 (rounded). Therefore, 0.428 x 100 will give you a percentage of 43%.
