kofi bought 4books at an average price of $2500 .if you the total cost of 3 books was $6500 .find the cost of the fourth book​

Respuesta :

6500 divided by 3 is 2166 2/3 and it works the other way around to 2166 2/3 multiplied by 3 = 6500 so the forth book would cost 2166 2/3 ps this is in fraction form
