Answer:
25 nickels, 60 dimes and 20 quarters
Step-by-step explanation:
Nickels, dimes and quarters
Nickel= 5 cents, dime= 10 cents, quarter= 25 cents
equations we get:
- 5n+10d+25q= 1225 ⇒ n+2d+5q= 245
if we subtract the first equation from the second we get:
considering d=3q, we have
then
so there are 25 nickels, 60 dimes and 20 quarters
