6. The first 65 bulbs sold had a cost of 65·$2.11 = $137.15.
The next 12 bulbs sold had a cost of 12·$2.31 = $27.72.
The remaining 128 - 65 - 12 = 51 bulbs sold had a cost of 51·$1.98 = $100.98.
The total cost of goods sold was $137.15 +27.72 +100.98 = $265.85
7. The remaining 108 - 51 = 57 bulbs have a value of 57·$1.98 = $112.86
8. The total cost of PRP inventory was
... $7,199.36 +16,090.80 +4,136.95 +20,965.00 = $48,392.11
The total number of units that purchased was
... 56 +132 +31 +175 = 394
So, the value of 165 monitors is 165/394 of the total cost.
... (165/394)·$48,392.11 = $20,266
9. The number on hand is the sum of receipts less the number of issues.
... 76 - 36 + 44 - 58 = 26 . . . . on hand on June 26th
10. Same as problem 9. The number on hand is the total of starting inventory and receipts less the number sold.
... 193 + 23 + 45 - 45 - 100 = 116
