<h3 /><h3>What were crude stone tool?</h3>
Any tool that is partially or totally fashioned out of stone is considered a stone tool in the broadest definition. Even if there are still societies and cultures that rely on stone tools, most of them are related to extinct prehistoric (especially Stone Age) cultures.
Archaeologists frequently research these prehistoric societies, and the examination of stone tools is known as lithic analysis. To deepen our understanding of the cultural ramifications of stone tool use and production, ethnoarchaeology has been a useful research field.
Arrowheads, spearheads, hand axes, and querns are just a few examples of the numerous tools made from stone throughout history. Stone can be ground into tools or it can be shaped by a flintknapper into knapped implements.

What is the present value of the cost of leasing?
Answer:
Cost of lease = $37,179.01
Explanation:
Leasing is a finance arrangement where one party (the lessor) transfers the right to use an asset to another party (the leasse) in exchange for a rent.
The cost of a lease to the leasee is the present value of the future lease payment discounted at the cost of capital.
So using the present value of annuity formula, we can work out the cost of the lease arrangement as follow:
PV =A× (1- 1+r)^(-n)/r
PV- Present Value
r- interest rate
n- number of years
A- annual lease payment
PV -
A-7,800
r-7%
n-6
PV = 7,800× (1- (1.07)^(-6)/0.07 = 37,179.01
Present Value = $37,179.01
Cost of lease = $37,179.01
