Answer:
January cost allocated 9,900
February cost allocated 11,790
Step-by-step explanation:
We will allocate the representative cost over the expected customer complaints during 2018:
$ 15,975 per month x 12 months / 21,300 complaints per year = $9 per complain solved
January processing customer complaints expense:
1,100 customers x $9 = $ 9,900
February processing customer complaints expense:
1,310 customers x $9 = $ 11,790
