The student council at Baruch is sponsoring a T-shirt sale. They plan to take orders in advance so they
know how many T-shirts to have printed. They have made the following estimates of expenses and
income for their sale:
• Expense of $350 for advertising plus $210 for using the printing press
• Expense of $4 for each T-shirt
• Income of $10 for each T-shirt
Income of $200 from a local business in exchange for printing the business's
logo on the back the T-shirts.
how many t-shirts must the student council sell to break even?
