Question 1175668: Translate the following mathematical statements into mathematical equations and solve the unknown
1. The amount raised during JS Promenade Night varies directly as the number of attendees and inversely as the amount of expenses used on the said event. If the amount of money raised for 250 attendees was Php5000.00 and the amount for expenses was Php4000.00 How much money will bhe raised for 300 attendees and Php6000.00 amount of expenses used during the JS Promenade Night?

M=k*A/E, Money is M, A attendees, E expenses
5000=k*250/4000
k=5000*4000/250=80000
-
M=80000A/E=80000*300/6000
M=4000
Another way of looking at it is the attendees for the second is 1.2 x that of the first and the cost is 1.5 times that of the first.
1.2/1.5=0.8
5000*0.8=4000Php
