Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
This can be done with simple concept of PERMUTATIONS AND COMBINATIONS.
The number can arrange themselves repeatedly to form different numbers. The possible number of ways they can do so is 3×2×1=6

ALTER,
You can arrange these number in 3!
