Question 3 (1 point) Galen wants to start a business making custom button-down shirts. He could pay $10 for a set of needles and thread that lasts one year and pay his friend Boris $5 a shirt to hand-sew the shirts, or he could buy a low-quality sewing machine that costs $200 a year to own and that sews shirts at a marginal cost of $1 per shirt. If it were also possible for Galen to buy a high-quality sewing machine that costs $650 per year to own and if, with this machine, he could sew shirts at a cost of $0.67 per shirt, it would be worthwhile for him to buy this high-quality sewing machine if he wanted to make __________ shirts per year.
Question 3 options: at least 1,350 no more than 675 at least 1,360 no more than 1,350 at least 675
