A party rental company has chairs and tables for rent. The total cost to rent
3 chairs and 5 tables is $ 57. The total cost to rent 12 chairs and 2 tables is $39. What is the cost to rent each chair and each table?
12c+2t=39....(1) 3c+5t=57....(2) Multiply the second equation -4 12c+2t=39 -12c-20t=-228 ............................ -18t=-189 Solve for t t=189/18 t=10.5. Plug in the first equation .............. 12c+2(10.5)=39 Solve for c C=1.5
