Sidana [21]

In the exercise Maxwell children want to calculate the estimated amount or budget placed on one person coming to the  anniversary party for their parents.

The number if guest will be 50 guests

Given data

quoted price = $96 per person

Let the total bill be x

<em>one-fourth of the total bill = 1/4*x</em>

advance payment is $1200 = 1/4x------------1

Let us find the total bill which is x

$1200 = 1/4x

<em>cross multiply</em>

1200*4 = x

x = 4800

if the budget per person is $96

Hence the total expected guest will be = 4800/96

50 guests
