Pat is hunting for sharks to take photos. For every photo he takes he earns $15. He sees a shark about every 10 minutes. His boat fuel costs $50 an hour. If he shark hunts for 5 hours, how much money can he expect to make in profit?
He will use $250 in fuel because 5 x 50 = <<5*50=250>>250
He will be shark hunting for 300 minutes because 5 x 60 = <<5*60=300>>300
He can expect to see 30 sharks because 300 / 10 = <<300/10=30>>30
He will make $450 off these photos because 30 x 15 = <<30*15=450>>450
He will make $200 in profit because 450 - 250 = <<450-250=200>>200
