Linear STAAR Review Questions

The total cost in dollars to buy uniforms for the company staff can be found using the function c = 14.95x + 7.95, where x is the number of uniforms bought. If there are at least 30 people but not more than 35 people on the staff, what is the domain of the function for this situation?

• 0 < x < 35

• 0 < c < 531.20

• {456.45, 471.40, 486.35, 501.30, 516.25, 531.20}

• {30, 31, 32, 33, 34, 35}
