Hi there!
Your question:
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows:
[(y2 - y1)/y1]*100=your percent change
y2= first value
y1=second value
Plug the numbers in:
[(300-270)/300]*100
[30/300]*100
0.1*100
10
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)

Answer:
the mark up used by the retailer is 115.12% of the wholesale price
Step-by-step explanation:
Mark-up is the percentage increase of the retail price over the wholesale price
Mark-up = (difference between retail and whole sale price / retail price ) x 100
difference between retail and whole sale price = $9.25 - $4.30 = $4.95
(4.95 / 4.3) x 100 = 115.12%.
