If the nail is 10 cents the hammer is 1.00
That would make the hammer cost 90 cents more than the nail. Hence it's the wrong answer..... It says the hammer costs 1.00 more than the nail, no .90 cents..
nah
he just did the math wrong
this question is constrained by 2 equations involved... not just one...
h + n = 1.10
h = n + 1
by substitution, 2n = 0.1
n = 0.05
