If 100<x<199 and 9<y<100, then the product xy CANNOT be equal to:  Pick one: A) 19,104 B) 19,303 C) 19,956.732 D) 19,502 E) 19,809
Correct Answer: (C)   Determine the range of xy by multiplying the two extremes of each individual range together. The smallest value of xy must be greater than 100 * 9. The largest value must be less than 199 * 100. This means that 900 &lt; xy &lt; 19,900. (19,956.732) is outside of this range, so it is not a possible product of xy.
