Kenna has different colored beads as shown. She wants to determine the total number of beads she has altogether.

• 24 green

• 17 purple

• 33 blue

• 26 pink

• Part A: Kenna explains there are a total of 820 beads because 4 + 7 + 3 + 6 = 20 in the ones place, so she writes down 20. Then 2 + 1 + 3 + 2 = 8 in the tens place, so she writes down 8 in front of the 20. Explain why Kenna’s reasoning is incorrect. Find the total number of beads she has altogether.
