Answer 3

let x = number of text messages sent

Answer 4

so if you send 1 message, then it will cost 0.05 dollars plus the monthly rate of $25

So one message will cost 0.05 + 25 = 25.05 dollars

---------------

2 messages will cost 0.05+0.05 or 0.05*2 = 0.1 dollars

Add this onto 25 to get 25+0.1 = 25.10 dollars total

---------------

3 messages will cost 0.05+0.05+0.05 or 0.05*3 = 0.15 dollars

Add this onto 25 to get 25+0.15 = 25.15 dollars total

---------------

See the pattern?

In general, sending x text messages will cost 0.05x dollars which adds to the $25 to get

0.05x+25

dollars total

Answer 5

Of course adding can be done in any order, so

0.05x+25

is the same as

25+0.05x
