The Hendersons are hosting a barbecue for five people and want to purchase enough chicken for everyone to have two pieces. Which option makes the most financial sense?

Five people need 5 × 2 = 10 pieces of chicken. Option A costs 10 × $3 = $30, while option D costs 5 × $5 = $25. The 12-pack costs $20 and provides enough for everyone, so it is the least expensive option that meets the need; the 20-pack costs more than necessary.
