参考答案：B

解析：

20×8 sales are expected to be $ 600 million ( $ 500 million 2007 sales×1.2 ) and 20×8 net income is expected to be $ 30 million ( $ 600 million 20×8 sales×5% ). 2008 non-cash operating working capital is expected to be $120 million ( $ 600 million 20×8 sales×20% ). The change in cash is expected to be - $ 5 million ( $ 30 million 20×8 net income + $ 60 million 20×8 depreciation - $ 2.0 million increase in non-cash operating working capital - $ 75 million 20×8 capital expenditures). The 20 x 8 ending balance of cash is expected to be $ 30 million ( $ 35 million beginning cash balance- $ 5 million decrease in cash).
