After a shipwreck, Tara is stranded on a desert island. She needs to build a shelter, so she makes an axe using materials from the wreckage and starts cutting down trees. There is a proportional relationship between the number of days Tara is stranded on the island, x, and the total number of trees she cuts down, y.
The equation that models this relationship is y=2x.
At this rate, how many total trees does Tara cut down in her first 3 days on the island? Write your answer as a whole number or decimal.
To find how many total trees Tara cuts down in her first 3 days on the island, we substitute x = 3 into the equation y = 2x:
y = 2(3) = 6
Therefore, Tara cuts down a total of 6 trees in her first 3 days on the island.
