A party rental company has chairs and tables for rent.

Question

The total cost to rent 2 chairs and 12 tables is $107.

The total cost to rent 5 chairs and 3 tables is $38.

Answer 1

2c+ 12t= 107

5c + 3t= 38

multiply 2nd by 4, then subtract 1st

20c+ 12t=38(4)=152

2c+ 12t=107

18c =152-107=45

c= 45/18= 5/2= $2,50=chair price

t=(107-5)/12 = 102/12=51/6= $8.50

t=(38-12.5)/3=25.5/3= $8.50= table price
