Question 1117737: The cost to rent a
condominium at the beach is $1,500 per week.
If two people share the cost, they each have to
pay $750. Explain why the relationship between
the cost per person varies inversely with the
number of persons sharing the cost. Then write
an inverse variation function that can be used
to calculate the cost per person, c, of p persons
sharing the rental fee.

Question 1123183: Suppose a rocket is launched into the atmosphere, and the function h determine's the rocket's height above the ground (in miles) given a number of minutes t since the rocket was launched.
a. What does the equality h(3)=539 tell us in this context? Select all that apply.
-539 minutes after the rocket was launched, the rocket is 3 miles above the ground
-The rocket is currently 539 miles above the ground
-The rocket travels 539 miles every 3 minutes
-3 minutes after the rocket was launched, the rocket is 539 miles above the ground
b. What does the equality h-1(970)=7 tell us in this context? Select all that apply
-The rocket is currently 970 miles above the ground
-If the rocket is 970 miles above the ground, 7 minutes have elapsed since it was launched
-The rocket travels 970 miles every 7 minutes
-If the rocket is 7 miles above the ground, 970 minutes have elapsed since it was launched
