The number of packs required is 6 and the amount spent would be $91.8
Part A :
Number of packs of bottle water needed :
- Number of guests / Number of bottles per pack
Now we have ;
Number of packs = 32 / 6 = 5.33
Hence, 6 packs of bottle water would be needed.
Part B:
Amount spent on bottle water:
- Cost per pack × number of packs
Now we have :
15.3 × 6 = $91.8
