Asked by McCormick

Hailey has 40 nickels and dimes and has a total of $2.85. How many dimes does she have?
'I got -23 nickels bit i don't think that's right.
Answered by Steve
23 nickels is right, but that wasn't what you were asked to find.
Answered by Ms. Sue
23 * 0.05 = 1.15

2.85 - 1.15 = 1.70

1.70 / 0.1 = 17

23 + 17 = 40

You're right!

Answered by Brady
Honestly, I think you are right.

nickels = 5 cents
dimes = 10 cents

23 x 5 = 115 - Or this could be $1.15

There are 17 remaining coins. These are dimes.

17 x 10 = 170 - Or this could be $1.70

Add the total dollar amounts:

$1.15 + $1.70 = $2.85

So, I think you are correct.

I hope this helps! :)

You're welcome McCormick. Ms Sue's way is a lot easier, I was just doing it the way that I would have double-checked it.
Answered by Reiny
number of nickels --- n
number of dimes ---- d

n+d = 40

5n + 10d = 285
divide by 5
n + 2d = 57

subtract the two equations:
d= 17
then in n+d = 40
n+17 = 40
n = 23
