Final answer:
The range of the function for buying uniforms for a basketball team with 10 to 15 players is $462.50 - $690.
Step-by-step explanation:
The cost to buy uniforms for a basketball team can be found using the function C = 45.50u + 7.50, where u is the number of uniforms bought. In this case, since there are at least 10 players but not more than 15 players on the team, we can substitute the values of u as 10 and 15 into the function to find the range of the function for this situation.
Substituting u = 10 into the function, we get C = 45.50(10) + 7.50 = 455 + 7.50 = 462.50.
Substituting u = 15 into the function, we get C = 45.50(15) + 7.50 = 682.50 + 7.50 = 690.
Therefore, the range of the function for this situation is $462.50 to $690.
