Due to restrictions, tonight's Varsity Volleyball game at WAHS can only have 25 spectators. Each ticket costs $6 online. The total amount of money WAHS will make can be found using the equation f(x) = 6x, where x is the number of spectators.

What is the domain of the situation?

• x is all real numbers

• 0 < x < 25 where x is an integer

• 0 < x < 6 where x is all non-negative integers

• x < 25

Juan is driving to Nevada, 2100 miles away. The distance, d(h), he has left to travel based on the hours driving, h, can be modeled by the function: $d(h)=2100-70h$  

What is an appropriate range for this situation?

• all real numbers  $\ge$  0

•  $0\le h\le30$  
  

•  $0\le d\left(h\right)\le2100$
