Answer: It will cost Mr. Miller $40.50 to rent the tables for his party.
Step-by-step explanation: To determine how many tables Mr. Miller needs to rent, you can use the ratio of 1 table for every 8 guests. With 72 guests, you can calculate the number of tables needed:
Number of tables = Total guests / Guests per table
Number of tables = 72 guests / 8 guests per table
Number of tables = 9 tables
So, Mr. Miller needs to rent 9 tables.
Each table costs $4.50 to rent, and he needs 9 tables, so the total cost will be:
Total cost = Number of tables × Cost per table
Total cost = 9 tables × $4.50 per table
Total cost = 9 × $4.50
Total cost = $40.50
It will cost Mr. Miller $40.50 to rent the tables for his party.
