Answer:
J = $350,000 + {0.30 Ă— [$50,000 + (0.50 Ă— J)]}
Explanation:
Data provided in the question
Janitorial Department (J) that includes $350,000 of direct costs and 30% of the Maintenance Department (M)
i.e., J = $350,000 + ( 30% Ă— M )
And
Maintenance dept. (M) includes $50000 of direct costs and also 50% of the janitorial dept. (J)
i.e., M = $50,000 + ( 50% Ă— J )
Therefore
The equation is shown below:
J = $350,000 + (0.30 Ă— M) and M = $50,000 + (0.50 Ă— J)
Now put the M values in the J equation
J = $350,000 + {0.30 Ă— [$50,000 + (0.50 Ă— J)]}
