Ariel has already spent 79 minutes on the phone and she expects to spend 4 more minutes with every phone call she routed. in all, how many phone calls does ariel have to route to spend a total of 131 minutes on the phone.

4

Step-by-step explanation:

1)  So the question is asking you how much phone calls you will need to get 131 minutes

2)now that you know that,you will have to divide 131 by 4 which is 32.75

3)so now you know that 32.75 is the unit rate so you will have to divide 131 minutes by 32.75

true? is that what you're asking or do you mean something else?

if x = 1, then the answer is 3.5
