Respuesta :
Since they give you the unknown "p" I'm assuming that you need to write out an equation and then solve... If we have 120 pencils and they are packaged into groups of 15, then we are dividing.
p = 120/15
p = 8
The teacher has 8 packages of pencils
p = 120/15
p = 8
The teacher has 8 packages of pencils
