\(1\)mét vải lụa và \(\frac{4}{5}\)mét vải hoa (hai lần của \(\frac{1}{2}\)mét vải lụa và \(\frac{2}{5}\)mét vải hoa) có giá là: 

\(23000\times2=46000\)(đồng) 

Giá tiền mỗi mét vài hoa là: 

\(\left(50000-46000\right)\div\left(1-\frac{4}{5}\right)=20000\)(đồng) 

Giá tiền mỗi mét vải lụa là: 

\(50000-20000=30000\)(đồng) 

Giá tiền \(8\)mét vải lụa và \(15\)mét vải hoa là: 

\(30000\times8+20000\times15=540000\)(đồng)
