A woman bought 210 oranges for 65.00 She sold all of them
at 3 for 2.00. How much
profit did she make?

Profit = 75

Step-by-step explanation:

Selling price of 3 oranges = 2

There are 210÷3 = 70 set of oranges

Selling price of 1 set (3 oranges) of orange = 2

Selling price of 70 set of oranges = 70 * 2 = 140

Cost of 210 oranges = 65

Profit = selling price - cost price

         = 140 - 65

         = 75
