The next time you need to make a choice, your brain will use what what method?
Katarina [22]

Answer:

Imagine you have just flicked a lighter. If you don’t see the flame, you will naturally try a second time. If after the second attempt it does not strike a flame, you will repeat your action again and again until it does. Eventually, you’ll see the flame and you’ll know that your lighter works. But what if it doesn’t? How long are you going to flick the lighter until you decide to give up?

Our everyday life is full of such decision dilemmas and uncertainty. We constantly have to choose between options, whether we make the most ordinary decisions – should I continue flicking this lighter? – or life-changing choices – should I leave this relationship? We can either keep on doing what we are already used to do, or risk unexplored options that could turn out much more valuable.

Some people are naturally inclined to take more chances, while others prefer to hold on to what they know best. Yet being curious and explorative is fundamental for humans and animals to find out how best to harvest resources such as water, food or money. While looking at the Belém Tower – a symbol of Portugal’s great maritime discoveries – from my office window, I often wonder what drives people to explore the unknown and what goes on in their brains when weighing pros and cons for trying something new. To answer these questions, together with Dr. Zachary Mainen and his team of neuroscientists, we investigate how the brain deals with uncertainty when making decisions.

Explanation:

It is well known that the decision-making process results from communication between the prefrontal cortex (working memory) and hippocampus (long-term memory). However, there are other regions of the brain that play essential roles in making decisions, but their exact mechanisms of action still are unknown.

During 2020, Stellar Furniture Company purchases a carload of wicker chairs. The manufacturer sells the chairs to Stellar for a
Ber [7]

Answer:

What is the amount of gross profit realized during 2020?

(460 x $33.30) + (230 x $29.60) + (276 x $18.50) = $27,232

What is the amount of inventory of unsold straight chairs on December 31, 2020?

[(920 - 460) x $56.70] + [(690 - 230) x $50.40] + [(1,610 - 276) x $31.50] = $26,082 + $23,184 + $42,021 = $91,287

Explanation:

lump sum cost of chairs = $137,655

Type                     Chairs       Selling Price Each       Total

Lounge chairs       920                     $90                 $82,800

Armchairs              690                     $80                   $55,20

<u>Straight chairs      1,610                     $50                $80,500</u>

total                      3,220                                          $218,500

if we allocate costs based on resale, then each chair should cost:

Lounge chairs $90 x ($137,655 / $218,500) = $56.70

Armchairs $80 x ($137,655 / $218,500) = $50.40

Straight chairs $50 x ($137,655 / $218,500) = $31.50

contribution margin per chair:

Lounge chairs $90 - $56.70 = $33.30

Armchairs $80 - $50.40 = $29.60

Straight chairs $50 - $31.50 = $18.50
