Answer:

The hourly wage of the assistant #color(blue)(=25$#

Explanation:

Let us denote the hourly wage of the assistant as #color(blue)(x#

So, as per the question the hourly wage of the instructor is :
#color(blue)(x)+15 $#

The combined hourly wage of both assistant #+# instructor

#color(blue)(x) +color(blue)(x)+15$ = 65 $#

#2x+15 = 65 #

#2x = 65-15 #

#2x = 50 #

#x=50/2#

#color(blue)(x=25$#

The hourly wage of the assistant #color(blue)(=25$#
