Answer 1

@Hero PLEASE HELP ME!

Answer 2

1st write 2 formulas. q = number of quarters....n = number of nickels
"Peggy had 3 times as many quarters as nickels."
q = 3n
"She had $1.60 in all"
0.25q + 0.05n = 1.60

Answer 3

I've had 5 people tell me this question is invalid.

Answer 4

Now use substitution. Plug in 3n for q in the second equation.
0.25(3n) + 0.05n = 1.6
0.75n + 0.05n = 1.6
0.8n = 1.6
n = 2
q = 3n = 3*2 = 6
2 nickels 6 quarters

Answer 5

6 is indeed 3 times as many as 2
and 6 quarters and 2 nickels make $1.60

Answer 6

It's solvable, but the given answer choices appear invalid

Answer 7

Okay, but that means there are the same number of quarters as nickles

Answer 8

Yeah, and that's where I'm stuck :(

Answer 9

Can't be the second choice since 160 is meaningless

Answer 10

yeah, nevermind.

Answer 11

Are they referring to $160 or 160 total coins?

Answer 12

160 cents?

Answer 13

$1.60

Answer 14

Yeah, 160 cents

Answer 15

I'm pretty sure it's an erroneous set of answer choices.

Answer 16

Yep, the setup is still wrong. You can't mix amount of money with number of coins.

Answer 17

I agree with you 100% hero.

Answer 18

The second one would work if it were:
5n + 25*3n=160
