Answer 7

Letty has $5 in nickels,dimes, and quarters. She has 3 times as many nickels as dimes. She has 5 times as much money in quarters as she does in nickels.

How many of each does she have??

.05n + .10d + .25q = 5.00 -- (100)
5n + 10d + 25q = 500

n = 3d
q = 5n --> q = 5(3d) --> q = 15d

when I sub all my d's in, I am getting the final result as a fraction

where am I messing up

Answer 8

d=3n, but good start

Answer 9

see..
5(3d) + 10d + 25(15d) = 500
15d + 10d + 375d = 500
400d = 500
d = 4/5

Answer 10

She has 3 times as many nickels as dimes

Does she have more nickels or dimes?

Answer 11

nickels.....n = 3d....??

Answer 12

uhm, I mean put d in terms of n not the other way around.... sorry that was nonsense before

Answer 13

d=1/3 n was what I meant

Answer 14

oh...use the d = 1/3n and the q = 5n instead of the d's ?

Answer 15

ea, but also let's think about that other one too
"She has 5 times as much money in quarters as she does in nickels."
to me that means 5(n*.05)=q*.25

Answer 16

she has 5 times as many quarters as nickels....Isn't that q = 5n ??

Answer 17

no, 5 times as much \(\color{red}{money}\)

Answer 18

hmmm..I guess that isn't the same.
so q = what ?

Answer 19

["She has 5 times as much money in quarters as she does in nickels."
to me that means 5(n*.05)=q*.25]

Answer 20

if you take the decimals out, would be 5(5n) = 25q : 25n = 25q ??

Answer 21

not quite, can't take the decimals out like that

Answer 22

so I shouldn't take the decimals out in the equation I multiplied by 100 ?

Answer 23

you would, get 500 not 5

Answer 24

\[\color{blue}{5} (.05n)=.25q\]

Answer 25

ohhh...I see now...thank you so much :)
