5. Dasha decided to sew dresses for 8 dolls. In the store, she chose a piece of fabric 140 cm long and 75 cm wide. Each dress requires a whole piece of fabric at least 45 cm long and 26 cm wide. Will the fabric Dasha bought be enough for all 8 dresses?
Solution. Let's cut the fabric from the store into two pieces measuring $140 \times 30$ and $140 \times 45$. From the first piece, we can cut out 3 blanks measuring $46 \times 26$, and from the second piece - 5 blanks measuring $45 \times 26$.

Answer: Yes, it will be enough.
