Answer 2

First, let's set up this problem.

f(x) = 0.08x + 10
How did I get this?
Well, f(x) says that this is a function. The 0.08 comes from the problem. The "x" variable multiplied by the 0.08 comes from how he gets charges 0.08 PER TEXT MESSAGE. The "per" is your key here. Next, he gets charged a FLAT RATE $10 fee.

We can set this up to look like
44.56 = 0.08x + 10
Since he was billed 44.56.
Next, we solve for "x" for the number of texts!

x = 432 texts.
