The questions to be answered before making a purchase are
the following;
<span>·
</span>What problems are most likely to happen? – an individual
should think of the problems that may arise based on his or her decisions
<span>·
</span>What could go wrong? – the individual should not
only be concerned with the purchase but what might happen after
<span>·
</span>What problems could be most damaging? – choices are
made available and to think about in order to think whether your choices could
cause problems or harm
Proof-of-Work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions on the distributed ledger or blockchain.
<h3>What is Proof-of-Work in Cryptocurrency?</h3>
- A type of cryptographic demonstration known as proof-of-work involves one party (the prover) demonstrating to another (the verifiers) that a certain amount of computational effort has been put forth.
- Consequently, this spending may be easily verified by verifiers with little work on their behalf.
- The goal of proof-of-work algorithms is not to demonstrate that a task was completed or that a computational challenge was "solved," but rather to prevent data modification by imposing onerous energy and hardware control constraints.
- Environmentalists have criticized proof-of-work systems for using too much energy.
- Later, Bitcoin popularized proof of work as the basis for agreement in a permissionless, decentralized network where miners compete to add blocks and create new money.

I believe it would be aluminium,
In order to refine new aluminium from the raw ore, companies need to spend a huge amount of resource which will diminish their profit.
Buying the recycled form on the other hand, is particularly easy and a whole lot cheaper for their cost.
Answer:
13.05%
Explanation:
Using CAPM Equation, Ke = Rf+Beta*(Rm-Rf)
= 0.045+1.3*(0.07)
= 0.136
= 13.60%
Using Dividend growth model, Ke = (D1/P0) + g
= (D0*(1+g)/P0) = g
= (1.50*(1+0.08)/36) + 0.08
= 0.125
= 12.50
The cost of equity (Ke) = 0.136 + 0.125 / 2
The cost of equity (Ke) = 0.261/2
The cost of equity (Ke) = 0.1305
The cost of equity (Ke) = 13.05%
