15 + 0.05x = 3 + 0.10x
-0.05x = -12
x = 240
So, at 240 texts companies 1 and 3 are the same.
UNDER 240 texts, company 3 is cheaper, which means that at 150 texts company 3 is cheaper.
Company 3 would cost:
3 + (0.10*150) = 18
Company 2 would cost 20, so company 3 is the cheapest of all 3
.
Happy learning,
