Ann has some dimes and quarters. if she has 25 coins worth 4.45 how many of each type does she have?
----------------------------
If she had 25 dimes, she'd have $2.50
Each dime replace by a quarter adds 15 cents
445 - 250 = 195
195/15 = 13 quarters
10 dimes
-------------
The hard way:
d + q = 25
10d + 25q = 445
etc
Same answer
