Answer:
So it will take 6 minutes to ring up 72 items.
Step-by-step explanation:
Well this seems pretty simple just have to reads the question and know what to find.
So what we know :
A cashier can ring up 12 items per minute
So :
1 minute = 12 Minutes
And we have to find :
How long for 72 items
So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.
So :
72 / 12
=
6
So it will take 6 minutes to ring up 72 items.
I hope this helps!

Step-by-step explanation:
The zeros are the values of x for which y = 0
Quadratic formula
x = [5 ± √(5² – 4·1·6)] / [2·1]
