But why is it "IF 5 cents"
OP says 10, not 5
Both items come to 1.10 total.the hammer has to be 1.00 more than the nail.
If the nail was 10 cents and the hammer was 1.00 the hammer would only be 90 cents more than the nail.
With the nail being 5 cents the hammer is 1.05
The hammer is 1.00 more and both add up to 1.10
Hence it's the correct answer.
