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? Choose 1 answer: B Yes; a legionary costs 1 denarius per day to support, and an archer costs 2 denarius per day to support. 4. Yes; a legionary costs 2 denarius per day to support, and an archer costs support. denarius per day to 3 No; the system has many solutions. No; the system has no solution.
