Anew company is purchasing a copier for their office. the table shows the costs associated with each copier. write a system of equations for this situation. then use a graphing calculator to estimate the number of copies that gives the same total cost. copier costs copier initial cost cost per copy a $700 $0.02 b $600 $0.06 let x be the number of copies and y be the total cost of printing x copies. write a system of equations for this situation. copier a yequals= ? copier b yequals= ?
