If x and y are two-digit integers such that x > 30 and y<70, which of the following is closest to the minimum value of xy?
Choose the correct choice from the following options.
A) 700 B) 460 C) 4,000 D) 310 E) 28,000
To get the minimum possible value of xy, we need minimize the value of both x and y   min x can be = 31 (given x is a two-digit integer &gt; 30)   min y can be = 10 (given y is a two-digit integer &lt; 70)   xy = 31*10=
