# Practice answer check

A2:B4 contains PR-101 $12, PR-102 $8, and PR-103 $25. Put ="PR-102"&CHAR(32) in E2; it evaluates to PR-102 plus one trailing ordinary space. LEN(E2) returns 7; LEN(TRIM(E2)) returns 6. =VLOOKUP(E2,$A$2:$B$4,2,FALSE) gives #N/A, while =VLOOKUP(TRIM(E2),$A$2:$B$4,2,FALSE) returns 8. The source SKU in A3 remains unchanged.
