Answer

Answer key: Party Drink worksheet

1. Total drinks to plan for: 289
1. Drinks per guest: 2 in the first hour plus 1 for each of the other hours
  $2 + 1 \times 5 - 1$ $= 6$
2. Multiply by the number of guests
  $45 \times 6$ $= 270 drinks$
3. Add the 7% safety margin and round up to whole drinks
  $270 \times 1 + \frac{7}{100}$ $= 288.9$ $= 289 drinks$
4. Split the drinks by share, rounding each up: beer 45%, wine 23%
  $289 \times 45%$ $= 131 beers$
5. Wine: a 750 mL bottle pours 5 glasses of 5 fl oz, so divide and round up
  $\frac{67}{5}$ $= 14 bottles$
6. Mixed drinks: a 750 mL bottle gives 16 pours of 1.5 fl oz, so divide and round up
  $\frac{35}{16}$ $= 3 bottles$
7. Mixer: 4 fl oz per mixed drink, in 2 L bottles
  $\frac{4,140.3 mL}{2,000 mL}$ $= 3 bottles$
