The denarius was a unit of currency in ancient rome. suppose it costs the roman government 10 denarius per day to support 3 legionaries and 3 archers. it only costs 3 denarius per day to support one legionary and one archer. use a system of linear equations in two variables. can we solve for a unique cost for each soldier?
a. yes; a legionary costs 1 denarius per day to support, and an archer costs 2 denarius per day to support. a yes; a legionary costs 1 denarius per day to support, and an archer costs 2 denarius per day to support.
b. yes; a legionary costs 2 denarius per day to support, and an archer costs 4/3 denarius per day to support. b yes; a legionary costs 2 denarius per day to support, and an archer costs 4/3 denarius per day to support.
c. no; the system has many solutions. c no; the system has many solutions.
d. no; the system has no solution. d no; the system has no solution.
