Problema Solution
A store buys a phone for $20. They mark it up 9/2 and then sell it at a 1/5 discount. What is the store's profit?
Answer provided by our tutors
buying price = $20
mark up = (9/2)*20
mark up = $90
discount = (1/5)90
discount = $18
selling price = 90 - 18
selling price = $72
profit = selling price - buying price
profit = 72 - 20
profit = $52
52/20 = 2.6 or 260%
store's profit is $52 or 260%.
