If 100<x<199 and 20<y<100, then the product xy CANNOT be equal to: Choose the correct choice from the following answers
A) 1900 B) 19,303 C) 19,356.732 D) 19,502 E) 19,909
Correct Answer: (A)   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 * 20. The largest value must be less than 199 * 100. This means that 2000 &lt; xy &lt; 19,900. (1900) is outside of this range, so it is not a possible product of xy.
