Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. how many toothpicks does she need to add to complete a 55-step staircase?

In the given question, there is no figure or diagram given. Based on the information's provided in the question the answer can be determined.
Number of toothpicks required by Ann to make 33-step staircase = 1818
Then
Number of tooth picks required
by Ann to make 55-step staircase = (1818/33) * 55
                                                       = (1818 * 5)/3
                                                       = 606 * 5
                                                       = 3030
So from the above deduction we can conclude that Ann needs 121 more toothpicks to complete the remaining steps.
So
The number of more toothpicks that Ann needs = 3030 - 1818
                                                                             = 1212
