If he sent 100 texts each month, that is a total of 400 texts during the 4 month period.
4(45.99) + 400x = 207.96
183.96 + 400x = 207.96
400x = 24
x = .06
Can you please help me! I solved it, but I'm not sure if I'm right.
------------------------------
Paulo pays $45.99 per month for unlimited calls, with additional charges for text messages. His bill for 4 months is $207.96. If he sends 100 texts each month, how much is he charged per text?
( Can you show an expression, seeing if I got it right! I got 16.666...)
I don't understand this, please help?
Substitute the cost of a text in the equation. Does it make a true equation?
