Acaterer is planning a large dinner party for 385 guests. each table must seat an equal number of gusts, more than 1 guest and fewer than 20. determine the number of possible table sizes. if the caterers use 7-person tables, how many tables will they need?

  The prime factorization of 1001 is 7*11*13, so with the constraint that the tables seat between 2 and 19 guests, we can use tables that seat either 7, 11, or 13 guests.

For tables that seat 7, the caterer would need 11*13 = 143 tables.

For tables that seat 11, the caterer would need 7*13 = 91 tables.

For tables that seat 13, the caterer would need 7*11 = 77 tables

Step-by-step explanation:

hopefully this is right

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
