messed up on last question. heres the actual one.

Aretha has $0.85 in nickels and dimes. She has 2 more nickels than dimes. How many nickels and imes does she have?

Need a formula for this problem.

These word problems are so hard. Help please!
I may have several more other questions after this.

thanks

Aretha has 7 nickles(35 cents)and 5 dimes(50 cents).7*5=35,5*10=50, and 35+50=85 cents!

Let N be the number of nickels

Let D be the number of dimes
N = D + 2
5N + 10 D = 85 (cents)
Now substitute to get rid of N
5(D+2) + 10 D = 85
15 D = 75
D = 5
N = 7

If you don't know algebra yet, you could solve this by trial and error, starting wth 8 dimes and 10 nickels (which is more than 85 cents), and then reducing (D,N) to (7,9),(6,8) etc until you find a combination that equals 85 cents.

You should start off where there are 2 more nickles than dimes. For, example 10 nickles & 8 dimes, 8 nickles and 6 dimes!

No problem! I can help you with that word problem and show you how to solve it.

Let's start by assigning variables to the unknowns in the problem. Let "n" represent the number of nickels and "d" represent the number of dimes Aretha has.

From the information given, we know that Aretha has $0.85 in nickels and dimes, and she has 2 more nickels than dimes.

First, we can express the total value of the coins in cents. The value of a nickel is 5 cents and the value of a dime is 10 cents. So, we can write the equation:

5n + 10d = 85 (in cents)

Next, we can express the relationship between the number of nickels and dimes using the given information. We know that she has 2 more nickels than dimes, so:

n = d + 2

Now, we have a system of equations:

5n + 10d = 85
n = d + 2

To solve this system of equations, we can use substitution. Start by substituting the value of "n" from the second equation into the first equation:

5(d + 2) + 10d = 85

Simplify this equation:

5d + 10 + 10d = 85
15d + 10 = 85
15d = 75
d = 5

Now, substitute the value of "d" back into the second equation to find the value of "n":

n = 5 + 2
n = 7

So, Aretha has 7 nickels and 5 dimes.

I hope this explanation helps! Let me know if you have any more questions.
