The calculation is as follows:
40800 × (3500 ÷ 70) ÷ 100 - 328 × 60= 40800 × 50 ÷ 100 - 328 × 60= 2040000 ÷ 100 - 19680= 20400 - 19680= 720
Therefore, the result is 720.
The calculation is as follows:
40800 × (3500 ÷ 70) ÷ 100 - 328 × 60
= 40800 × 50 ÷ 100 - 328 × 60
= 2040000 ÷ 100 - 19680
= 20400 - 19680
= 720
Therefore, the result is 720.
