The week in numbers to September 26

The big and small numbers that grabbed attention - or should have - in the business world over the past week.

Monday:

85 cents - Independent senator Nick Xenophon is worried that Woolworths' move to sell its homebrand bread for 85 cents could cripple independent retailers. It's food for thought.

Tuesday:

8.41 per cent - Shares in Tesco tumbled after the British supermarket giant overestimated its half year profits by STG250 million ($A456 million). The miscalculation sent Tesco's share price sliding almost 12 per cent. It later pulled back but was still down a hefty 8.41 per cent at 210.3 pence on London's FTSE 100 index.

Wednesday:

20 per cent - US soft-drinks giants have promised to work to reduce the country's beverage calorie consumption by 20 per cent by 2025. Coca-Cola, PepsiCo and Dr Pepper Snapple pledged to provide smaller-sized bottles, and more water and other no- or low-calorie beverages, to the market. There's 10 teaspoons of sugar in a 375ml can of Coke.

Thursday:

20 per cent - Fancy a seachange to tropical Darwin? A survey by RP Data shows that the number of properties listed for sale in Australian capitals is 11.6 per cent lower than in September 2013 - except in Darwin. There, the number for sale in Darwin is up by 20 per cent.

Friday:

$US80,000 - A truck dripping rancid juices from thousands of kilos of rotting chicken sat in the heat for more than a month at a Montana truck stop, where an irate trucking company employee abandoned it. The driver left the trailer containing about 17,000 kilos of frozen chicken near the Flying J Truck Stop west of Missoula after the company refused his requests for more money. The chicken was worth $US80,000 ($A86,556)
