One start$-$up office is deciding between two photocopier options. The first is to lease a high$-$end machine for $\backslash$$$8,000/$year$.$ The lease is all$-$inclusive so the only additional costs are the cost of paper, which is $\backslash$$$0\mathrm{.}15/$sheet$.$ The other option is to lease a low$-$end machine $.$ The cost is $\backslash$$$5,000/$year and the per sheet cost increases $($toner $,$ maintenance $)$ to $$0\mathrm{.}25.$ Which option is less expensive if the annual copy volume is expected to be $60,000$
