$4,125
Step-by-step explanation:
Calculation of the amount of warranty liability which should be reported at December 31, 2021
First step
Sales(Cellphone) × Percentage of sold phone ×Average repair cost
($690 x 10%) =$69
$69×$75
=$5,175
Second step

=$5,175-$1,050
=$4,125
Therefore the amount of warranty liability which should be reported at December 31, 2021 is $4,125
