Answer:

9. the yellow bag

Step-by-step explanation:

  • Green bag=2.59/7=0.37
  • Blue bag=4.56/12=0.38
  • Yellow bag=6.30/18=0.35

0.35<0.37<0.38

I am only gonna help with this one cus I also have homework~sorry!!
For #9 the 18 ounce packet has the lowest cost per ounce
I know this because for the 7 ounce packet it is $0.37 per ounce, for the 12 ounce packet it is $0.38 per ounce and for the 18 ounce packet it is $0.35 ounce a packet. So the lowest is the 18 ounce packet.
I hope this helped.
