Can you explain the formulas that will explain the following charts?

Per Lorenzo's request, you also decide to see what effect a price increase might have on Lorenzo's $\backslash$table$[[$Lorenzo$\text{'}$s Data$],[$Selling price,,$[$Insert value$]],[$Variable Costs$],[$Cost for paper, per unit,$[$Insert value$],],[$Cost for printing, per unit,$[$Insert value$],],[$Cost for film, per unit,$[$Insert value$],],[$Total Variable Costs,,$[$Insert value$]],[$Contribution Margin,,$[$Insert value$]],[$Fixed Costs$],[$Staff salaries,$[$Insert value$],],[$Other operating costs,$[$Insert value$],],[$Total Fixed Costs,,$[$Insert value$]],[$Breakeven Sales Units,,$[$Insert value$]],[$Target Profit Goal,,$[$Insert value

position. You have noticed that Lorenzo's is one of the only poster shops in the area, and customers may

be willing to pay more, and a higher price may even signal higher quality. Though, there are no

guarantees that the market will accept the price increase. Lorenzo is looking at increasing the sales price

to $$9\mathrm{.}25.$

You let Lorenzo know that you will do an analysis of all options and present your recommendations

when you are done.
