Question

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 days will it take Tara to cut down a total of 12 trees? Write your answer as a whole number or decimal.

Answer 1

To find the number of days it will take Tara to cut down a total of 12 trees, we need to substitute y = 12 into the equation y = 2x and solve for x.
12 = 2x
Dividing both sides by 2, we get:
x = 6
Therefore, it will take Tara 6 days to cut down a total of 12 trees.
