Question

Tim's phone service charges $25.16 plus an additional $0.21 for each text message sent per month. If Tim's phone bill was $30.41, which equation could be used to find how many text messages, x, Tim sent last month?





$0.21x - $25.16 = $30.41







$25.16x - $0.21 = $30.41







$0.21x + $25.16 = $30.41







$25.16x + $0.21 = $30.41

\(\large\color{slate}{ 25.16 +0.21x= 30.41 }\)

Answer 3

solve this equation for x..
0.21 is a cost per call, x is the [unknown] number of calls.

Answer 4

first subtract 25.16 from both sides, and then divide both sides by 0.21

Answer 5

Well I am so dumb that I still don't get it.. Sorry though... :(
