Answer 1

n+3n=1.60

Answer 2

I've had 8 people tell me the answers are invalid

Answer 3

But that would mean there would be the same number of nickles as quaters

Answer 4

I mean that nickles and quaters have the same value

Answer 5

I'm pretty sure I'm right.

Answer 6

Nickels are 5 cents and dimes are ten cents.

Answer 7

@phi

Answer 8

I'm gonna ask hold on

Answer 9

none of those equations work, unless they explain what n means

if n means # of nickels , and q = # of quarters you can say
q= 3n (the quarters are three times as many as nickels )
and
0.25q + 0.05n = 1.60

replace q with 3n to get
0.25(3n) + 0.05n= 1.60

if we multiply by 100:
25*3n +5*n = 160

or
75n + 5n = 160

80n= 160
n=2

Answer 10

none of those equations quite match your choices.

Answer 11

notice we can simplify the first equation
n+3n=1.60
to
4n= 1.60
n= 0.40

40 cents means nothing ! (the answer is 2 nickels and 6 quarters... and 40 cents is not relevant.)

for the last two equations
5n+3n=1.60
8n= 1.60
n= 0.20
20 cents is also irrelevant.

You are the victim of a GOOFY question!

Answer 12

@Hero
Sorry to bug you again, but what equation did you say would be needed to make this equation true
