You and your classmates decide to sell sweatshirts and T-shirts to raise money for a school trip. You decide that you should sell at least thirty items, but do not want to exceed 120 items. Based on a small survey of students, you also decide that the number of T-shirts should be at least twice the number of sweatshirts. Write the inequalities, then assume the profit for sweatshirts is $5 and the profit for T-shirts is $2. What's the max profit?
