How does the following program execute?

Flowchart has $3$ variables $($integer numItems, float rate, float total$)$ and $5$ nodes. Node $1$ is the start node and points to node $2.$ Node $2$ code: numItems $=2$ Node $2$ points to node $3.$ Node $3$ comment: $//$numItems $=4$ Node $3$ code: rate $=0\mathrm{.}5$ Node $3$ points to node $4.$ Node $4$ code: total $=$ numItems $*$ rate Node $4$ points to node $5.$ Node $5$ is the end node.
