A furniture factory makes 5 recliners for every 2 couches. If the factory makes a total of 154 recliners and couches in a day, how many recliners were made?

Respuesta :

5C = 2R
C = 2/5 R
R + C = 154
2/5R + R = 154
2/5R + 5/5R = 154
7/5R = 154
7R = 770
R = 110

C = 44

110/44 = 5/2  (Double checking)
they made 11 and 1 left over
