(A) $800 (B)$900
(C) $1050 (D)$1250
(E) $1300 Total fixed expense $$= 250$$ Let variable expense depending on the number of guests attending the party be $$= x$$ For $$10$$ guests the total expense was estimated = Fixed expense + variable expense of $$10$$ guests $$= 250 + x$$ For $$10$$ guests the total expense was estimated to be $$= 650$$ $$250 + x = 650$$ $$x = 650 - 250 = 400$$ For $$10$$ guests variable expense is $$400$$. Therefore for $$20$$ guests variable expense will be twice $$= 800$$ Estimated total expense for $$20$$ guests $$= 250 + 800 = 1050$$ Answer (C)...

(E) $1300 Fixed Expense = 250 Variable Expense = 650-250 = 400 Variable Expense/Person = 400/10 = 40 Variable Expense for 20 people = 40 x 20 = 800 Total Expense for 20 people = 800+ 250 = 1050.

(A) $800 (B)$900
(C) $1050 (D)$1250
(E) $1300 We can create the following equation in which x = the cost per guest: 250 + 10x = 650 10x = 400 x = 40 Thus, for 20 guests, the total cost is 250 + 20(40) = 1,050 dollars.
