Answer:
1. Ending balance of cash short and over account:
Ending cash = 100 beginning balance + Cash register amount - Actual cash counted
July 2 = 100 + 281.80 - 379.00
= $2.80 shortage because actual cash is less than it should be
July 9 = 100 + 311.50 - 411.50
= $0
July 16 = 100 + 304.10 - 406.90
= $2.80 surplus because actual cash is more
July 23 = 100 + 318.20 - 416.00
= $2.20 shortage
July 30 = 100 + 293.60 - 397.50
= $3.90 surplus
Balance = Surplus - shortages
= (3.90 + 2.80) - (2.80 + 2.20)
= $1.70
2. This is revenue because it is a surplus.
