carlos and sarawong are selling wrapping paper.Customers can buy rolls of plain wrapping paper and shiny wrapping paper.Carlos sold 11 rolls of plain wrapping paper and 6 rolls of shiny wrapping paper for total of 154$.what is the cost of each of one roll of plain wrapping and one roll of shiny wrapping paper

Assume the cost of one roll of plain wrapping is x and cost of one roll of shiny wrapping is y

so, 11*x + 6*y = 154

to determine the value of x and y i.e. the value of one roll of plain and shiny wrapping papers, we need at least one more relation between x and y.

Hence this question is incomplete. Kindly check the question and see if there is any more information given (which has to be). I will solve it immediately
