Here are the solutions to the questions.

If each block costs GHC 1.80 and the cost of labour is one-third the cost of a block, find the total cost of laying the blocks.

Recall the number of blocks required from part (a).
From part (a), 175 blocks were required.
Calculate the cost of one block.
Cost per block = GHC 1.80.
Calculate the cost of labour per block.
Cost of labour per block $= \frac{1}{3} \times \text{Cost per block}$
Cost of labour per block $= \frac{1}{3} \times 1.
