Answer:

#$5# for the day

Explanation:

6:40am to 7:40 = 1 hour

He walked the dog from 6:40am to 7:30am

#:.7:40am - 7:30= 10# minutes short from 1 hour

So he walked the dog for 50 minutes in one day.

His rate per hour #= $ 6#

1 hour = 60 minutes

#:.=$6# per hour ( per 60 minutes)

#:.cancel50^5/cancel60^6 xx $6#

#:.5/cancel6^1 xx $cancel6/1#

#:.=$5# for 50 minutes work for one day

Answer:

# $5 #

Explanation:

Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was # 50 # minutes. Also a note, an hour is # 60 # minutes.

Since he is paid at a rate of # $6 # per # 60 # minutes, we can make a proportion.

# 6/60 = x/50 #

From here, you have to solve for # x #. So cross multiply, and then simplify.

# 60x = 50 * 6 #

# (60x)/60 = (50 * 6)/60 #

# (cancel(60)x)/cancel60 = (5cancel0 * 6)/(6cancel0) #

# x = (5 * cancel6)/cancel6 #

# x = 5 #

So the answer is # $5 #.
