I get $5 every 10 seconds how much would I have in 500 mins

You would earn $15,000 in 500 mins

First you want to find how many "10 seconds" are in 500mins. To do this convert 500 mins to seconds by multiplying 500 by 60 which will give you 30,000. Next divide 10 by 30,000 which will be 3,000. With that you can multiply by 5 to get how much you would earn in 500 mins. 5*3,000=15,000.
