So one month at silver gym and a class costs $55 in total. One month at fit factor and one class costs $85 in total.

In order to have the same prices for both gyms, Sarah would have to buy 2 personal training classes from silver gym. $25+ $30= $55+$30=$85. (The price of fit factor)

Option A. is correct for the given condition.

Lets solve it through steps of range and functions,

First of all, Solve the equation:
$f(x) = |x|+5$
$= > x = -5$ (1)

$= > x = 5$ (2)

So these would be the ranges of X in between 5 and -5.

Hence option A. $R{f(x)eR [f(x) < 5}$ is correct.
