Answer 1

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:

• n+d+q= 105

• 5n+10d+25q= 1225 ⇒ n+2d+5q= 245

if we subtract the first equation from the second we get:

• d+4q= 140

considering d=3q, we have

• 3q+4q=140

• 7q=140

• q=20

then

• d=3*20= 60

• n=105-(20+60)= 25

so there are 25 nickels, 60 dimes and 20 quarters
