I need to see step by step on how you get the answer to this

In a commercial kitchen, fruit is processed in two steps, CUT and BLEND.

The first step, CUT, takes 30 seconds per ounce of peeled and destoned/deseeded fruit. There are 16 ounces in 1 pound.

The second step, BLEND, takes 3 minutes per pound of fruit.

Between each fruit type, the blender has to be cleaned for 20 minutes.

Let's start with a batch size of 1 pound of fruit (B = 1 pound) and calculate the capacity for each step.

For B = 1 pound, the capacity (in pounds/hour) of CUT = [1 pound/(1 pound x 0.5 minutes/ounce x 16 ounces/pound) ] x 60 minutes/hour.

For B = 1 pound, the capacity (in pounds/hour) of BLEND including the setup time = [ 1 pound/(20 minutes + 1 pound x 3 minutes/pound) ] x 60 minutes/hour.

Which step is the bottleneck?
