Joshua Tree Corp is a firm that only produces durable hiking backpacks.Imagine that their production can be modeled by the following Cobb-Douglas production function:

=^0.7

Where K is a measure of capital input and L is a measure of Labor.

1. If they experience increasing returns to scale, what is the minimum value for?

2.Now assume that= 0.9, K=100, and L=75. How many backpacks would Joshua Tree Corp. produce at these levels of inputs.

3.How many would they produce if they doubled their levels of input?

4.How many times greater is their production in part c than it is in part b? Relate this to Joshua Tree Corp's return to scale.
