Cara has a cafe and also sells pastries (at $4 apiece) to go with her coffee drinks.She currently buys pastries from a local bakery for a discounted price of $2.10/each, but she is considering whether to install an oven (at a cost of $581/month) to make them herself, as the variable cost with baking is only $.45 per pastry.How many pastries would Cara have to sell per month to prefer making them herself with the expensive installed oven instead of buying them from the bakery?Please keep your answer in fractional units (even though nobody would sell part of a pastry) to at most 1 decimal place
