Trey made some biscuits, muffins and brownies.

4/7 are biscuits, 1/3 of them are muffins and the rest are brownies. There are 160 more muffins than brownies.

How many biscuits, muffins and brownies does Trey have altogether?

Let the total of biscuits, brownies and muffins be x

The number of biscuits = 4/7x

The number of muffins = 1/3x

The number of brownies = x (4/7x+1/3)

                                                               =x-19/21x

                                                                 =2/21x

                                                      1/3x-2/21x=160

                                                          => 5/21x=150

                                                              x=672

So,

Number of biscuits = 384

Number of muffins = 224

Number of brownies = 64
