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.
Yes; a legionary costs 111 denarius per day to support, and an archer costs 222 denarius per day to support.
Can we solve for a unique cost for each soldier?
