Answer:
a. Predetermined administration costs - $ 54 per engineering hours
b. Profit per Toot - $ 648,075
Profit per Tix $ 326,450
Step-by-step explanation:
Computation for predetermined overhead rate for admin costs
Estimated administration costs $ 629,100
Engineering hours - Toot - 6,825
Engineering hours - Tix - 4,825
Total engineering hours 11,650
Predetermined rate for administration costs
$ 629,100/ 11,650 hours $ 54 per hour
Computation of total profit for each service
Administration costs - Toot = 6,825 hours * $ 54 per hour = $ 368,550
Administration costs - Tix = 4,825 hours * $ 54 per hour = $ 260,550

Revenues 1,350,000 1,040,000
Engineering costs 333,375 453,000
Allocation of admin costs 368,550 260,550
Total costs 701,925 713,550
Profit per service 648,075 326,450
