The total number of whales in the sea this year is double what it was last year. If the World Animals Organization predicts that there will be 800 more whales in the sea next year, and the number of whales in the sea last year was 4000, calculate the total number of whales in the sea next year if the predictions are accurate.
How many whales are there this year? ** If there were 4000 whales in the sea three years ago, and their number doubled this year, then there are 2*4000 = <<4000*2=8000>>8000 whales in the sea this year.
How many whales will there be next year? ** If the predictions come true, there will be 8000+800 = <<8000+800=8800>>8800 whales in the water next year.
