using the feedback below correct the original work to make the calcualtions correct 
review the cumulative frequency column and also re look at the histogram. Reworking those two pieces will be helpful — hint — Are you sure you want all the sales to be the same outside of the QC Sparkle?
Original instructions 
Using Brent’s last four weeks of sales data, organize Liège sweet specialty waffle sales in a 
frequency distribution table, then complete the three problems below. 
Data from the last four weeks of Sweet Addie’s Liège specialty waffle sales:
Red, White, and Oreo: 1st week=10 waffles, 2nd week=10 waffles, 3rd week=15 waffles, 4th week=15 waffles
Addie’s Fav: 1st week=10 waffles, 2nd week=20 waffles, 3rd week=25 waffles, 4th week=25 waffles
The Elvis:  1st week=10 waffles, 2nd week=20 waffles, 3rd week=30 waffles, 4th week=40 waffles
Queen City Sparkle: 1st week=20 waffles, 2nd week=10 waffles, 3rd week=8 waffles, 4th week=5 waffles
Holy Cannoli: 1st week=10 waffles, 2nd week=10 waffles, 3rd week=8 waffles, 4th week=7 waffles
Create a frequency distribution table of weekly Liège waffle sales, also show relative frequency, relative frequency percentage, and cumulative frequency.  
Create an appropriate histogram showing how the weekly sales frequencies are distributed across the five Liège waffles.
Interpret your results in a brief paragraph. Address the following: 
What are the Liège waffle dishes that make up at least 50 percent of Brent’s sales? 
What are the waffle dishes that make up at least 75% of overall Liège waffle sales?  
Based on the knowledge that many of the ingredients are expensive (i.e. Pearl Sugar), which Liège waffle dishes would you recommend Brent keep on the menu and which waffle dishes should he discontinue? Using relative frequency percentage and cumulative frequency as your evidence, explain your recommendations.
