The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation?

• 0 < u < 12

• 0 < c < 425.65

• {8, 9, 10, 11, 12}

• {285.85, 320.80, 355.75, 390.70, 425.65}

A student rode a bike from school to a recreation center. The graph shows the student's distance in miles from the recreation center after riding the bike for x minutes.
