You are developing a performance progress report for a project you are managing. The following time$-$phased budget was developed earlier in the planning stage and is being used as the standard against which the project performance is measured.

$\backslash$table$[[\backslash$table$[[$Work$],[$Packages$]],$W$1,$W$2,$W$3,$W$4,$W$5,$W$6],[$A$,8,2,2,,,],[$B$,,,,6,,],[$C$,,,,,10,7],[$Total$,8,2,2,6,10,7]]$

You are analyzing the project performance at the end of Week $2.$ Activity $"$A$"$ is $50\%$ complete and its actual cost is $5.$ What is the cost variance of this activity?

Use two decimal places in your calculations.
