I'm struggling with this topic. Can someone help me understand how to answer these? Thank you!

1. Break-even point: Algebraic Kate Rowland wishes to estimate the number of flower arrangements she must sell at $25.49 to break even. She has estimated fixed operating costs of $11,650 per year and variable operating costs of $15.51 per arrangement. How many flower arrangements must Kate sell to break even on operatingcosts?

The operatingbreak-even point is _________. (Round to the two decimal places.)

2. Break-even comparisons: Algebraic Given the price and cost data shown in the accompanying table for each of the threefirms, F,G, andH:

a.The operatingbreak-even point for company F is ___________(Round to the two decimal places.)

The operatingbreak-even point for company G is ___________(Round to the two decimal places.)

The operatingbreak-even point for company H is __________(Round to the two decimal places.)

b. In order from most risky to leastrisky, the companies are ranked ______________

3. Break-even point: Algebraic and graphical Fine Leather Enterprises sells its single product for $129.56 per unit. Thefirm's fixed operating costs are $473,800 annually, and its variable operating costs are $86.46 per unit.

a..The operatingbreak-even point is __________ units. (Round to the two decimal places.)

b. Draw the graph that correctly depicts the operatingbreak-even analysis?
