Answer:

She made the profit of $ 20

Step-by-step explanation:

Given,

The original cost price of the bicycle = $ 50,

After selling it to $ 60,

Profit = selling price - cost price = 60 - 50 = $ 10,

Again after purchasing it for $ 70 and selling it to $ 80,

Profit = 80 - 70 = $ 10

Hence, the total profit = 10 + 10 = $ 20
