• Lana has different colored buttons as shown. She wants to determine the total number of buttons she has altogether.

• Green: 24

• Purple: 22

• Black: 35

• White: 29

Part A: Lana explains there are a total of 846 buttons because 4 + 2 + 5 + 9 = 20 in the ones place, so she writes down 20. Then 2 + 2 + 3 + 2 = 9 in the tens place, so she writes down 9 in front of the 20. Explain why Lana’s reasoning is incorrect. Find the total number of buttons she has altogether.
