be used so that the total monthly cost without the discount
pass is the same as the total monthly cost with the discount pass.

12 times

Step-by-step explanation:

Without the discount pass, the bus fare is $1.25. The monthly discount pass is $15.00. 15 ÷ 1.25 is 12. So, the bus would have to be used 12 times in a month so that the total monthly cost without the discount pass is the same as the total monthly cost with the discount pass.
