First, let's calculate the total number of bands Jenny has for each color.
-
Red Bands:
- Bands per Bag: 80
- Bags Purchased: 3
- Total Red Bands = 80 bands/bag × 3 bags = 240 bands
-
Blue Bands:
- Bands per Bag: 60
- Bags Purchased: 3
- Total Blue Bands = 60 bands/bag × 3 bags = 180 bands
-
Green Bands:
- Bands per Bag: 72
- Bags Purchased: 3
- Total Green Bands = 72 bands/bag × 3 bags = 216 bands
-
Yellow Bands:
- Bands per Bag: 48
- Bags Purchased: 3
- Total Yellow Bands = 48 bands/bag × 3 bags = 144 bands
Now, let's add all the bands together to find the total number of bands:
\[ \text{Total Bands} = \text{Total Red Bands} + \text{Total Blue Bands} + \text{Total Green Bands} + \text{Total Yellow Bands} \]
\[ \text{Total Bands} = 240 + 180 + 216 + 144 \]
Calculating step by step:
- \(240 + 180 = 420\)
- \(420 + 216 = 636\)
- \(636 + 144 = 780\)
Now, Jenny divides the total number of bands (780) equally into 4 kits:
\[ \text{Bands per Kit} = \frac{\text{Total Bands}}{4} = \frac{780}{4} = 195 \]
Therefore, the number of bands in each kit is 195 bands.
