Answer
The answer and procedures of the exercise are attached in the following archives.
Step-by-step explanation:
Gross profit = Sales - Cost of goods sold
= (440 x 90 + 220 x 80 + 264 x 50) - (440 x 56.7 + 220 x 50.4 + 264 x 31.5)
= (39,600 + 17,600 + 13,200) - (24,948 + 11,088 + 8,316)
= 70,400 - 44,352
= $26,048
