Answer:
M=p-5n
Step-by-step explanation:
Here we are given that M+5n=p
We are asked to solve this equation for M. In order to do that we will follow these steps.
Subtracting 5n from both sides we get
M+5n-5n=p-5n
M=p-5n
Hence , now we have our M as dependent variable, whose value depends on the values of p and n. One or both of them can be independent variable/.

Answer:
The indifference point is 140 minutes.
Step-by-step explanation:
Giving the following information:
Plan A costs $ 25 plus an additional $0.10 for each minute of calls.
Plan B costs $18 plus an additional $0.15 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
<u />
Plan A= 25 + 0.1*x
Plan B= 18 + 0.15*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
25 + 0.1x = 18 + 0.15x
7 = 0.05x
140=x
The indifference point is 140 minutes.
<u>Prove:</u>
Plan A= 25 + 0.1*140= $39
Plan B= 18 + 0.15*140= $39
It would be: 2 × x + 4 + 2× x
= 2x + 4 + 2x
= 4x + 4
In short, Your Final Answer is 4x+4
Hope this helps!
