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.
C. 3/2 divided by 3
Alina has 3/2 hours to complete her homework. She should divide her 3/2 hours by the 3 assignments to determine how much time she will spend on each assignment. This turns out to be 1/2 hours, or 30 minutes, on each assignment. 3/2 hours is the same thing as 90 minutes, so this answer makes sense. We want the time to be divided by the number of assignments, not vice versa.
6.5-3.5-2.25
