If a skilled wrapped does 4000 egg rolls in an 8-hour day, then he does 4000 / 8 = 500 egg rolls per hour. It means that he can make 500 / 60 = 8,(33) egg rolls per minute. So Bettie's claim is not reasonable.
It would be reasonable if the wrapper would make 1 * 60 = 60 egg rolls per hour and 60 * 8 = 480 egg rolls in one shift. So she's far away from truth :)
Hope this helps!

The third digit can be any digit except the digits you chose for the first and second digit - 8 possibilities.

Step-by-step explanation:
1/2(6x+1/2)=0
3x+1/4=0
3X=-1/4
X=3(-1/4)
X=-3/4
OR
X=-.75
