I'm trying to do a Trial Balance worksheet and this is what I have to do, I believe these go in the adjustments section.

a. Unexpired insurance balance at December 31, 2008: $2,500
b. Supplies on hand at December 31, 2008: $500
c. Depreciation on building for the year: $1,300
d. Depreciation on equipment for the year: $4,500

A. In my unadjusted trial balance I have
Prepaid Insurance Debit:7,200

Do I credit 2,500 in the adjustments Leaving Debit:4,700 in the adjusted trial balance?

B. My supplies is
Supplies Debit:1,980
So I should Credit 500? Leaving Debit:1480 in adjusted?

Am I on the right track?
