400
Mrs. Lau needed $1.00 from every 2nd grader for a new recorder. Students are only allowed to give her one kind of dollar bill or only the same kinds of coins. What are some ways that students can pay her? (Example: only dollars, only quarters, only pennies, etc.)
They could give her $1.00 bill, 2 half dollars, 4 quarters, 10 dimes, 20 nickels, or 100 pennies.
