Appetizers: $9.20
Buffet: $18.30
Sit down dinner: $25.75
Hall: $250
Linens: $15 per table
Table and chair rental (seats 8): $60 per table
From the given information, there will be
(125 people)/(8 seats per table) = 15.625 => 16 tables.
The cost of renting tables and chairs = 16*60 = $960.00
Appetizers for 125 people will cost 125*9.20 = $1150.00
Buffet for 125 people will cost 125*18.30 = $2,287.50
The cost for the hall = $250.00
The cost for linens = (16 tables)*($15 per table) = $240.00
Total cost, before taxes, is
960.00 + 1150.00 + 2287.50 + 250.00 + 240.00 = $4,857.50
Answer: $4,857.50
