Brian has 5 times as many quarters as dimes if the total value of her coins was $16.20 how many of each kind of coin did she have

Q=number of quarters

d=number of times

1q=25 cents

1d=10 cents

total is 1620 cents

25q+10d=1620

divide both sides by 5 to simplify

5q+2d=324

also

5 times as many quarters as dimes

q=5d

sub 5d for q

5 (5d) + 2d=324

25d+2d=324

27d=324

divide both sides by 27

d=12

sub

q=5d

q=5 (12)

q=60

60 quarters

12 dimes

She would have 5 dimes and 60 quarters I think sorry if im wrong; c
