Question 590978
a parking meter contains $27.05 in dimes and quarters. There are 146 coins in the meter. How many of each type are in the meter?
----------------
d + q = 146
10d + 25q = 2705
Can you finish it?
--------------------
Or,
If it's 146 dimes, it's worth 1460 cents.
Each dime replaced by a quarter adds 15 cents.
2705 - 1460 = 1245
1245/15 = q
