How many coach tickets did she​ buy?

Answer 1

Answer:

she bought 8 coach, 2 first-class

Step-by-step explanation:

let x = number of coach tickets

equation I used:  320x + 960(10 - x) = 4480

                            320x + 9600 - 960x = 4480

                            -640x = -5120

                             x = 8
