If marco walks 5 dogs for 12 minutes each, how much money will he earn?

Since Marco makes 10$ an hour for every dog he walks, we need to see how much money he would make per minute.

To find out how much money he makes per minute, we divide 10.00 by 60.

10.00÷60= 0.16666

Since it's an extended decimal we round it, so he makes about $0.17 per minute.

Next, we multiply 0.17 by 12, so we know how much money he makes every twelve minutes. 

0.17×12=2.04

He makes around $2.04 every twelve minutes.

Since he's walking 5 dogs, we multiply 2.04 by five.

2.04×5=10.20

That means he earns $10.20.

I hope you have a wonderful day! :D
