They will make the same amount after 10 phones sold. Before that Plan A is the better plan. After 10, Plan B is the better plan.
You can find the point of intersection by modelling the two equations and setting them equal to each other. If x is equal to phones sold:
250 + 25x = 50x
250 = 25x
10 = x
Therefore, you make the same at 10 phones.
Answer:
maybe it's D ( not sure tho)
Hey there!!
How do we find the midpoint?
We take the average , the average is =
Sum of the observations / total number of observations
The end points are given as 4 and 11
Sum = 11 + 4
Number of observations = 2
= 15 / 2
= 7.5 is the midpoint
