Laylah as already spent 3 minutes on the phone, and she expects to spend 1 more minute with every phone call she routes. If she routes 23 phone calls, how much time will Layla have spent on the phone in total?

Step-by-step explanation:

Let x represent the number of phone call that she routes.

Laylah has already spent 3 minutes on the phone and she expects to spend 1 more minute with every phone call she routes. This means that if she routes x phone calls, the total number of time that Layla would have spent on the phone is

3 + x

If she routes 23 phone calls, the total time that Layla would have spent on the phone in total is

3 + 23 = 26 minutes
