How many T-shirts must the company sell this year in order to
earn $56,640 in net income?
Crane sells T-shirts imprinted with high school names and logos. Last year the shirts sold for $26 each, and variable costs were $14.00 per shirt. At this cost structure, the breakeven point was 45,000 shirts. However, the company actually earned $21,600 in net income. This year, the company is increasing its price to $28 per shirt. Variable costs per shirt will increase by...
