Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
= 
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.

Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row
