Out of the \$500 charged per person, the organization deposits \$125 andthe hotel charges \$295.

Amount per person for the organization to recover the fixed cost of \$20000

= \$(500 - 125 - \$295)

= \$80

Number of registrants necessary for the organization to recover the fixed costof \$20000

= 20000/80

= 250

Amendment :

In above, "\$(500 - 125 - \$295)" should be "\$(500 - 125 - 295)".

Alternative method :

Let n be the number of registrants required.

(500 - 125 - 295)n = 20000

80n = 20000

n = 250

Hence, number of registrants required = 250
