x=5, y= 1.73*5+80.13 =88.75 pounds

At the age of 6, the weight will be;

x=6, y=1.73*6+80.13 = 90.15

Difference in weight after one year increase of age will be;

90.15-88.75=1.73

This means after a year, a boy gains 1.73 pounds

There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.
