4. We need to find out how many packs Libby needs to buy.

2. Solution Steps

To find the number of packs needed, we need to divide the total number of yoghurts by the number of yoghurts in each pack.
Packs=Total yoghurtsYoghurts per packPacks = \frac{Total\ yoghurts}{Yoghurts\ per\ pack}
Packs=2904Packs = \frac{290}{4}
Packs=72.5Packs = 72.5
Since Libby can only buy whole packs, she needs to buy enough packs to have at least 290 yoghurts. Therefore, we round the number of packs up to the nearest whole number.
Packs=73Packs = 73

3. Final Answer

Libby needs to buy 73 packs.
