In the financial pages of a newspaper, one can sometimes find a table (or matrix) listing the exchange ratesbetween currencies. In this exercise we will considera miniature version of such a table, involving onlythe Canadian dollar (C$) and the South African Rand(ZAR). Consider the matrix
representing the fact tha C$1 is worth ZAR8 (as ofSeptember 2012).
a. After a trip you have C$100 and ZAR 1,600 in yourpocket. We represent these two values in the
