# Practice answer check

All six orders total $540. Filtering Region to East leaves H-101 $120, H-103 $45, H-104 $200, and H-106 $35, so SUBTOTAL(9,C2:C7) returns $400 and SUBTOTAL(103,A2:A7) counts 4 visible order IDs. Filtering to West leaves H-102 $80 and H-105 $60, returning $140 and a count of 2. Manually hiding East row H-103 changes SUBTOTAL(109,C2:C7) to $355 but leaves SUBTOTAL(9,C2:C7) at $400 while the East filter is active. Code 103 counts 3 visible IDs after that manual hide. Restore every hidden row before comparing the two filter results.
