An entrepreneur buys some microscopes. Each one cost $200 and resells online for $526. What is the mark-up percentage?

Dafna11 [192]

Answer:

326

Step-by-step explanation:

Given: Microscopes. Each one costs $200 and resells online for $526.

To find: What is the mark-up percentage?

Solution: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

$526 - 200 = 326$

Net Profit Margin = 61.98%

Net Profit = $326.00

Profit Percentage = 163.00%
