Question 697279: The cost of hiring a bus for a trip to Niagara Falls is $400. The cost per person varies inversely as the number of people who will go on the trip. How much will each person pay if 25 people go on the trip?
my work:
x=cost per person
y=number of people
x(25)=400
divide out 25 from both sides and get $16.00.
I'm not sure if i did the problem right when it says varies inversely.

x(25)=400
X=400/25=$16.00 IS CORRECT.
INVERSE MEANS AS THE NUMBER OF PEOPLE INCREASE THEN THE AMOUNT DECREASES.
THUS: IF YOU HAVE 40 PEOPLE THEN THE PRICE IS:
40X=400
X=400/40
X=$10.00 PER PERSON.
ALSO IF THERE ARE ONLY 16 PEOPLE THEN.
16X=400
X=400/16
X=$25.00
