Thus, the required value is
Since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "h" next to the 15. so you would have 15h and then put a plus 5 to show her transportation fee. so you would have the equation of 15h+5
E=15H+5
H=(E-5)/15
