$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 .

$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
