Part A: Jeanie’s Button Collection

Colors and Counts:

• 24 blue

• 18 green

• 27 red

• 31 yellow

Jeanie explains there are a total of 1,002 buttons because 4 + 8 + 7 + 1 = 20 in the ones place, so she writes down 20. Then 2 + 1 + 2 + 3 = 8 in the tens place, so she writes down 80 in front of the 20 and says the total is 1,002. Explain why Jeanie’s reasoning is incorrect. Find the actual total number of buttons she has.
