Answer:
£103
Step-by-step explanation:
He wants the least waste possible.
So if he buys a 180 cm piece he can make 3*65 cms pieces, with only 6 cm waste.
Now he needs wood for 2*65 and 2*110 pieces which is a total length of
340 cms. That would require 1 * 150 pieces for the 65 cms and 2 for the 110 cm pieces. Total 3 * 150 cm pieces.
Answer is 1 * 180 and 3*150 pieces.
Total cost 28 + 3*25 = 103.
