Answer:
235,000 total overhead
Explanation:
First we calculate the rate for activity
[tex]\left[\begin{array}{cccc}&Cost&Pool&Rate\\Setups&60,000&24,000&2.5\\Inspections&120,000&24,000&5\\Assembly&280,000&28,000&10\\\end{array}\right][/tex]
Next, we apply this rate to desk lamp
[tex]\left[\begin{array}{cccc}&Rate&Desk&Overhead\\Setups&2.5&16,000&40,000\\Inspections&5&15,000&75,000\\Assembly&10&12,000&120,000\\\end{array}\right][/tex]
Total Overhead will be the sum of each activity overhead
40,000.00 + 75,000.00 + 120,000.00 = 235,000 total overhead
