£ 84

Explanation:

Step 1:

Here totally 5 pieces each of 65 cm and 2 pieces of 110 cm woods are needed. Then the total sum is


(5*65)+(2*110) = 545 cm

Step 2:

100 cm wood costs £ 21

150 cm wood costs £ 25

180 cm wood costs £ 28

To be economical 3 180 cm woods are sufficient for Jerry. (
3*180 = 540 cm )

Therefore Jerry should pay a total cost of £ 84 and it is the lowest amount that Jerry could pay.
