Your surf shop sells two types of surfboards. The first, type A, costs $294 and you make a $24 profit on each one. The second, type B, costs $143 and you make a $20 profit on each one. You can order no more than 120 surfboards this month, and you need to make at least $2,560 profit on them. If you must order at least one of each type of surfboard, how many of each type of surfboard should you order if you want to minimize your cost?
