Expansion Costs
The local manger of a nearby Stone Mine has recently contacted the kingdom
advisors to ask permission to upgrade his Mine by an additional 70 square metres
on top of the already built 140 square metres.
After reviewing his request the Council declined to allow him to upgrade 70sqm,
but instead opted that 60sqm would be enough, and that they would offer a ten
percent deduction on the cost of any materials brought from the royal warehouse
custody not including Tools since they are brought in a constant supply.
Now this manager has been running the mine for so long he is considered a
Huckster in the eyes of the council, so every additional squared metre costs him
120 wood, 60 stones and 12 tools.
Buying from the royal warehouse these materials cost him 24¢τ for each fathom of
wood, and the same for Stone, although he can get this from the Mine itself.
Tools are priced at 12¢τ each, although he already receives a five percent
discount on these from buying at a constant level for use in the Mines.
So he already has a supply of Stone from his Mine, but needs to buy enough Tools
and Wood for this upgrade in size.
He also needs to hire constructors to build this extension who charge at a rate
of 1,200¢τ per squared metre.
Once the construction is complete he also needs to hire six new employees at a
charge of 2,000¢τ each.
Question:
How much in ¢τ would the manager need to spend in total for the construction of
his mine extension?
Remember to take into account any discounts and the amount of materials he
actually needs. |
Hint: This is a mathematical problem, think
carefully using paper if necessary.

Solution of last edition
The
Apples are priced as follows;
Red: 7¢τ
Yellow: 6¢τ
Green: 9¢τ
Adela originally purchased Six Yellow, Nine Green and
Five Red apples. This would have come to a total of 152¢τ.
Now a few people submitted this as the answer, however the question asks what
would she have spent on the apples she actually brought home.
After leaving the market place Adela ran into her friend Tristana, and traded
one red apple for two yellow apples. So in effect she traded a
red apple worth 7¢τ for two yellow apples worth 12¢τ.
This would have brought her total spenditure to 157¢τ, which was also
submitted as a possible answer.
However on her way home she ate one of the Yellow Apples so when
she did arrive it would be that she traded only one red, for one yellow -
in effect bringing home, Seven Yellow, Nine Green and Four
Red apples.
Recalculating the totals at this point would have meant she spent 1¢τ less on
her original total bringing us to the answer 151¢τ.
And so for the prizes?
