Answer :
To determine how many more metres of wire the builder needs to finish fencing the garden, we can use a simple subtraction operation.
Total wire needed:
The builder requires a total of 150 metres of wire.
Wire already available:
The builder already has 68 metres of wire.
Calculation:
To find out how many more metres are needed, subtract the amount of wire the builder already has from the total amount required.
[tex]150\, \text{metres (total needed)} - 68\, \text{metres (already have)} = 82\, \text{metres (more needed)}[/tex]
So, the builder needs 82 more metres of wire to finish fencing the garden.
This problem involves basic arithmetic and is a common type of question to practice subtraction and understand resource allocation.
