If a and b are two-digit integers such that a > 20 and b<60, which of the following is closest to the maximum possible value of ab ?
Choose the most appropriate option
A) 700	B) 2,800	C) 5,841	D) 7,000	E) 28,000
To get the maximum possible value of ab, we need maximize the value of both a and b   max a can be = 99 (given a is a two-digit integer &gt; 20)   max b can be = 59 (given b is a two-digit integer &lt; 60)   xy = 99*59=
