Question 658996
Let x = # of tables made with method 1, y = # of tables made with method 2


Hours:


1x+1.5y = 88


x = 88 - 1.5y



Cost:


7x+6y = 526


7(88 - 1.5y)+6y = 526


7(88-15y)+6y=526


616-10.5y+6y=526


-4.5y+616=526


-4.5y=526-616


-4.5y=-90


y=(-90)/(-4.5)


y=20


x = 88 - 1.5y


x = 88 - 1.5(20)


x = 58


So you should make 58 tables using method 1 and 20 tables using method 2
