You should make graph or chart, like November, one panda eats 30 of bamboo each day. and there are 30 days in November. So what I would do is multiply 30 x 30. 30 pounds x 30 days = 900 pounds. So, the average amount that one giant panda eats in November is 900 ponds of bamboo
Ok set the necklace as X and the bracelet as Y X+Y=192 X=3Y Plug in 3Y for X in the first equation 4y=192 Y=48$ Plug that into your second equation X=3(48) X=144$
