Answer:
There 138 quarters and 0 nickels.
The value of nickels is $0.
Step-by-step explanation:
A quarter is 0.25 of a dollar, and a nickel is 0.05 of a dollar. We are told that the total worth of nickels and dollars we have is 34.5, that is
where is the number of quarters, and is the number of nickels.
We are also told that total number of coins is 138, that is
so we have two equations:
To this system of equations we first solve for in second equation and substitute its value into the first equation:
the first equation becomes
So we have 138 quarters.
Now we put this value into equation(2) and solve for
So we have 0 nickles and therefore their value is $0.
