Respuesta :

Since "x" is the amount of hours that he works and it is stated that he works for 8 hrs, you would plug 8 into the equation instead of "x" 
15(8) + 10 instead of 15x + 10
When you simplify this you will get 120 + 10 which equals 130 (answer D)
Saha1
15x+10
x=8
15(8)+10
(15×8)+10
120+10
130
