$60

Let #x# be the earnings for 6 hours.

#($400)/(40hrs)=($x)/(6hrs)#

Multiplying both sides by 120,

#1200=20x#
#x=60#

She earns #$60# in #6# hours.

Let #x# equal the amount of money she earns in #6# hours.

#400/40 = x/6#

Cross multiply

#400(6)=40x#

#2400=40x#

#2400/40 = (40x)/40#

#60=x#
