The prompt

A fictional online grocer in São Paulo has an average order of BRL 120, with a gross margin of 22 percent on the groceries. For each order it pays BRL 6 to pick and pack, BRL 9 for delivery, and payment fees of 2 percent of the order. Each small warehouse (a dark store) costs BRL 90,000 a month to run. How many orders a day does a dark store need to break even?
