Which of the following independent changes would cause a company’s breakeven point to increase (go up)?

The following was reported on sales of two products: Sales mix photo.png a. What is the sales mix (% or ratio) based on units? [BLANK-1] Green [BLANK-2] White b. Assuming the current sales mix remains constant, compute the breakeven in total units and broken down by product. Show calculations on your work paper and enter your final answers in the spaces provided. [BLANK-3] Total units [BLANK-4] Units of Green [BLANK-5] Units of White [BLANK-6] b. Would the breakeven in total units increase, decrease, or stay the same if the sales mix shifted to fewer units (lower proportion) of Green and more units (higher proportion) of White? 

The information below was reported when 3,600 units were produced and sold:    Units sold 3,200    Sales $76,800    Variable costs $48,000    Fixed costs $17,100    Compute the following. Show your calculations on your work paper and type in your final answers in the spaces provided. Type in only numerals, no dollar signs ($) or commas. $[BLANK-1] Compute the contribution margin per unit. Compute the breakeven point in units and dollars. [BLANK-2] Breakeven units $[BLANK-3] Breakeven sales dollars $[BLANK-4] What is the margin of safety in dollars? [BLANK-5]% What is the margin of safety ratio (percentage). (Round to one decimal XX.X) [BLANK-6] Compute the degree of operating leverage at the current sales level (round to 2 decimals). [BLANK-7] If the tax rate is 30%, how many units must be sold to earn a net income (after tax) of $9,450?
