Imagine |you |are |developing |an |algorithm |to |calculate |the |total |cost |of |a |purchase |order |that |
contains |several |items. |The |cost |of |each |item |and |the |tax |rate |is |known. |The |standard |shipping
|charge |for |the |entire |order |is |$4.95, |and |the |special |delivery |charge |is |$19.95. |In |addition, |


there |is |no |tax |on |the |shipping |cost. |Which |of |the |following |is |the |correct |pseudocode |for |the |
required |algorithm? |- |CORRECT |ANSWER✔✔-For |each |item |on |the |purchase |order:

,| Order |cost |= |order |cost |+ |item |cost

If |standard |shipping

| Shipping |cost |= |4.95

Else

| Shipping |cost |= |19.95

Total |purchase |order |cost |= |order |cost |* |tax |rate |+ |shipping |cost



What |is |the |purpose |of |the |following |algorithm, |written |in |pseudocode?

num |= |0

Repeat |the |following |steps |10 |times
