The sales for iPhones were 100 iPhones * $1000 per iPhone on average = $<<100*1000=100000>>100,000

The sales for iPads today were 20 iPads * $900 per iPad = $<<20*900=18000>>18,000

The sales for Apple TV’s today were 80 * $200 = $<<80*200=16000>>16,000

The total sales for Apple at their New York store today was $100,000 + $18,000 + $16,000 = $<<100000+18000+16000=134000>>134,000

The total number of products sold was 100 + 20 + 80 = <<100+20+80=200>>200

The average cost per product sold was $134,000 total sales / 200 total products = $<<134000/200=670>>670
