Adele spent 8 minutes on the phone while routing 2 phone calls. If she routes 4 phone calls, how much time will Adele have spent on the phone in total? Solve using unit rates.

Respuesta :

Answer:

16 minutes

Step-by-step explanation:

Given

Represent minutes with M and Phone calls with P.

When M = 8; P = 2

Required

Determine M when P = 4

First, we need to determine the constant of proportion using:

[tex]M = k * P[/tex]

Where k represents the constant:

[tex]8 = k * 2[/tex]

Divide through by 2

[tex]4 = k[/tex]

[tex]k = 4[/tex]

Solving for M, when P = 4

Substitute 4 for P and 4 for k in [tex]M = k * P[/tex]

[tex]M = 4 * 4[/tex]

[tex]M = 16[/tex]

Hence:

She spent 16 minutes in total
