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.
f(x) = 0.08x + 10

Given Data
- Amount per text sent = $0.08
- Extra fee = $10
- Total bill = $44.56
First, let us get the Mathematical expression for the scenario
Total = 0.08*x + 10
Substituting our given data into the expression to find x we have
44.56 = 0.08x+ 10
44.56-10= 0.08x
34.56 = 0.08x
Divide both sides by 0.08
x = 34.56/34.56
x = 432
