Step-by-step explanation:

Katie's deposits are positive: 23.87, 41.03, and 61.33.

Her withdrawals are negative: - 4.34 - 21.11, - 8.78.

Sorted from least to greatest (most negative is least, most positive is greatest):

-21.11, - 8.78, - 4.34, 23.87, 41.03, 61.33

Katie started with $128. Add to it all the deposits and withdrawals:

128 - 21.11 - 8.78 - 4.34 + 23.87 + 41.03 + 61.33 = 220
