Hello, My question is there any way to calculate this on the calculator HP 10bll+ ??

Here is the question with the answer, I am looking for instruction how to calculate this on Financial caclulator:

Question 7

You are considering an equipment purchase costing $167,000. This equipment will be depreciated straight-line to zero over its three-year life. What is the average accounting return if this equipment produces the following net income?

Year Cash Flow

1 15,600

2 14,200

3 13,500

a) 18.29 percent

b) 18.38 percent

c) 15.67 percent

d) 17.29 percent

Answer

AAR = [($15,600 + 14,200 + 13,500)/3]/[($167,000 + 0)/2] = .1729, or 17.29 percent

Here is my guessing what I put on calculator:

CALCULATOR

CFJ 0: 15,600

CFJ 1: 14,200

CFJ 2: 13,500

and than what else??
