Soro bought a $50.00 bus card at the beginning of the week. each bus ride costs $2.50. he needs to have at least $20.00 on his card at the end of this month. to determine how many bus rides he can take between now and the end of this month, soro wrote and solved the following inequality:

To answer this item, we let x be the number of bus rides that Soro will be able to take from the beginning of the week to the end of the week. The amount  she will have to spend for x tickets will be 2.5x. Then the amount she will have left after the purchase is,
                                            50 - 2.5x
This value should be at least 20. The inequality that best represent the situation is,
                                          50 - 2.5x ≥ 20
