Answer 1

Activity Rates

Consultation $150

Drawings $58

Modeling $0.7

supervision $190

Billings $1037.5

Collections $1642.5

Total overhead allocated: $ 126,826

Step-by-step explanation:

First, we divide the cost of each activity over the base total to get the rate.

`\left[\begin{array}{ccccc}$Activity&Driver&cost&Total&Rate\\$Consultation&$contact hours&315000&2100&150\\$Drawings&$desing hours&104400&1800&58\\$Modeling&$square feet&32200&46000&0.7\\$supervision&$days&228000&1200&190\\$Billings&$jobs&8300&8&1037.5\\$Collections&$jobs&13140&8&1642.5\\\end{array}\right]`

Now we apply this rate against the job activity measurement:

`\left[\begin{array}{ccccc}$Activity&Job&$Rate&$Allocated\\$Consultation&410&150&61500\\$Drawings&352&58&20416&\\$Modeling&7400&0.7&5180&\\$supervision&195&190&37050&\\$Billings&1&1037.5&1037.5&\\$Collections&1&1642.5&1642.5&\\$Total&&&126826&\\\end{array}\right]`
