Question 956924: a shopper purchased 4 tables and 2 chairs for $434. Another shopper purchased 2 tables and 7 chairs for $451. what is the cost for each table and each chair? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 4T+2C=434 DIVIDE BY 2 & SUBTRACT.
2T+7C=451
-(2T+C=217)
----------
6C=234
C=234/6
C=$39 FOR EACH CHAIR
4T+2*39=434
4T+78=434
4T=434-78
4T=356
T=356/4
T=$89 FOR EACH TABLE.
PROOF:
2*89+7*39=451
178+273=451
451=451
