If 100
If 100<x<199 and 9<y<100, then the product xy CANNOT be equal to:
Answer/Solution
19,956.732
Steps/Work
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 < xy < 19,900. (C) is outside of this range, so it is not a possible product of xy.
