Answer:

an needs to walk dogs for at least 9 hours in order to earn more than $520 a week.

Step-by-step explanation:

Since his car wash attendant job pays $400 a week then you can subtract that from your final revenue.

$520-$400=$120

Now, to find out how many hours he has to walk dogs for in order to earn more than $520, you need to know some basic multiplication so...

$15×8=$120

...but he needs to earn MORE than $520 so...

$15×9=$135

$400+$135=$535.

makvit [3.9K]

Answer:

1200

Step-by-step explanation:

We can gather from what's given that y=20x

y represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.
