To determine the total number of shirts produced in the factory, we start by denoting this number as \( x \).
The problem gives us the following information:
- 15% of the shirts are defective.
- 20% of the remaining shirts are sold in the domestic market.
- The remaining 8840 shirts are left for export.
Let's solve the problem step-by-step:
- Calculate the total defective shirts:
Defective shirts = \( 0.15x \) - Determine the shirts that are not defective:
Non-defective shirts = \( x - 0.15x = 0.85x \) - From these non-defective shirts, 20% are sold domestically:
Domestic market shirts = \( 0.20 \times 0.85x = 0.17x \) - The remaining shirts are for export:
Export shirts = \( 0.85x - 0.17x \)
Export shirts = \( 0.68x \)
We know these shirts are 8840, so:
\( 0.68x = 8840 \) - Solve for \( x \):
\( x = \frac{8840}{0.68} \)
\( x = 13000 \)
Therefore, the total number of shirts produced in the factory is 13000.
