Question 761416
Kate has 21 coins (nickels and dimes) in her purse. How many nickels and dimes does she have if she has $1.50?
----------
Another approach:
If she had 21 dimes it would be $2.10
Each dime replaced by a nickel reduces the amount by 5 cents.
210 - 150 = 60
60/5 = 12 nickels
--> 9 dimes
