First, list a bar for 100 guests. Based on the number of actual guests, simply apply a modifier to get an accurate estimate.
For example, you expect 135 guests. Based on the 100-guest rule you will need 12 cases of spirits & wine, simply multiply each number by 1.35 to get an accurate total for 135 guests. For events with fewer than 100 guests, reverse the process.
