Here's a quick answer off the cuff.
\r
\n" ); document.write( "\n" ); document.write( "Doing simple multiplication, find the highest product of 13 less than 100 (the lowest possible 3-digit number). In this case, the closest you can get is 13*7=91
\r
\n" ); document.write( "\n" ); document.write( "Now find the highest product of 13 greater than 999 (the highest possible 3-digit number). In this case it's 13*77=1001
\r
\n" ); document.write( "\n" ); document.write( "So we can now easily see that the products of 13 that are 3 digit numbers are exclusively given as:
\r
\n" ); document.write( "\n" ); document.write( "{8, 9, 10...75,76,77} or {8 through 77}
\r
\n" ); document.write( "\n" ); document.write( "To find the actual amount of products in that range, just subtract 8 from 77
\r
\n" ); document.write( "\n" ); document.write( "\"77-8=69\"
\r
\n" ); document.write( "\n" ); document.write( "There are 69 3-digit numbers divisible by 13, so the answer is C!!! :)
