Question 387717: joe has a nickles and dime that is worth $2.15. if the number of dimes was doubled and the number of nickles was increased by 28 , the value of the coins would be $6.00. How many nickles and dimes does he has?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
Let = number of nickels
Let = number of dimes
given:
(1) (in cents)
(2)
----------------------------------
There are 2 equations and 2 unknowns,
so it's solvable
(2)
(2)
Now subtract (1) from (2)
(2)
(1)
impossible
In (1), has to be odd to get
In (2), ends up being odd again
and that can't give me
These numbers are wrong somehow, I think.
