It's just asking of all the number of wings that were left behind in bucket which one is the smallest number which is 1.
This is simple , minus 50 from 100 and that gives you 50 left . then divide that by 2 and that gives you 25 . so the minimum number of sales required is 25 . hope this helps :)<span />
7/8 can be converted to .875 because 1/8 is .125 and .125*7=.875. Add -12 to it so the answer is -12.875
<span>3.7 x 10^<span>4 that is the answer</span></span>
