IF speed 50 then
fine = 2000

(a) With the aid of a trace table, write the output that would be displayed
for the variable fine after tracing through the above pseudocode (the
NESTED-IF design) if the user entered the following data for
speed?
Speed
50
90
140
35
(b) Based on your evaluation, is the pseudocode above correct or incorrect?
Justify your answer, and state how, if at all, the pseudocode should be
corrected.
