John Braun admired his wife's success at selling scarves at local craft shows, so he decided to make two types of plant stands to sell at the shows. John makes twig stands from twigs he collects from a friend's farm, so his variable cost is minimal (wood screws, glue, and so forth). However, John has to purchase wood to make his oak plant stands. His unit prices and costs are as follows: B (Click the icon to view the data.) The twig stands are more popular, so John sells four twig stands for every one oak stand. Mary charges her husband $400 to share her booth at the craft shows (after all, she has paid the entrance fees). How many of each plant stand does John need to sell to break even? Will this affect the number of scarves Mary needs to sell to break even? Explain. Determine how many of each plant stands John needs to sell to break-even. Begin by computing the weighted average contribution margin per unit.
