Answer: There is 49.28% of cumulative markup for the department at the end of April.
Step-by-step explanation:
Since we have given that
Price of opening inventory = $170,000
Mark up rate = 48%
Amount of mark up is given by
[tex]\dfrac{48}{100}\times 170000\\\\=\$81600[/tex]
Price of additional merchandise = $80000
Mark up rate = 52%
Amount of mark up is given by
[tex]\dfrac{52}{100}\times 80000\\\\=\$41600[/tex]
So, total mark up would be
$81600 + $41600 = 123200
So, the cumulative markup percentage for the department at the end of April is given by
[tex]\dfrac{123200}{170000+80000}\times 100=\dfrac{123200}{250000}\times 100=49.28\%[/tex]
Hence, there is 49.28% of cumulative markup for the department at the end of April.
