The price per person to rent a limousine for a prom varies inversely as the number of passengers. If 5 people rent the limousine, the cost is $70 each. How many people are renting the limousine when the cost per couple is $18.50?
---------------------
p = k/n
70 = k/5
k = 350
------------
Equation for this limo:
p = 350/n
How many people are renting the limousine when the cost per couple is $18.50?
Note: If couple pays 18.50, p = $9.25
---------------
9.25 = 350/n
n = 350/9.25
n = 37.84
Rounding up you get n= 38
