1. Beginner seamstress Alyona decided to sew 8 dresses for 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 purchased fabric be enough for everything?
Answer. Yes, enough.

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 $45 \times 26$, and from the second piece - 5 blanks measuring $45 \times 26$.

Comment. A correct example of arranging 8 blanks (in the form of a verbal description or a drawing with size indications) is given - 7 points. Only a correct drawing without size indications - 5 points. If minor arithmetic errors are made in the description that do not affect the solution - deduct 1 point. Only the answer without justifications - 0 points. The problem is solved incorrectly - 0 points.
