Question 1129206: Three companies offer a decent package for texting only on cellphones. The first company is 15$ per month with an additional 0.05$ per text. The second company's offer is 20$ unlimited texting and the third company offers 3$ per month with an additional 0.10$ per text. Which company has the best offer for 150 texts per month? Found 2 solutions by addingup, MathTherapy:Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! 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
.
