This problem can be solved using a system of equations.

If we call the number of nickles n and the number of dimes d, we can write the following two equations:

n + d = 42 (The number of nickels and dimes is 42)

.05n + .1d = 3.35 (5 cents for every nickel plus 10 cents for every dime is $3.35)

Then:

n + d = 42

5n + 10d = 335 (Switch to cents instead of dollars, gets rid of decimals)

n = 42 - d

We have now just defined n in terms of d. Now every time you see n in the second equation, you can replace it. This is called substitution.

5n + 10d = 335 (from above)

5(42 - d) + 10d = 335 (substituting for n)

Follow through with the algebra, and d (# of dimes) = 25, then there must be 17 nickels.

25 dimes, 17 nickels

Q: You save 42 nickels and dimes that total 3.35 how many nickels and dimes do you save?

It's very simple, actually! There are 365 days in a year, right? If you save five minutes every day for 365 days, you multiply 5 by 365 to find out how many minutes total you saved that year.

49 and 51 for example. Save 48; 52 47; 53 etc. Save

$18.87

70% of 50 is what number? The answer right now is pretty pointless, so I'm going to save you all time and say the answer is 35.

4500 + (45 x 13 x 7) = 8595 simple interest. 4500 x (1.13)7 = 10586 annual compound interest

During 1942-45 nickels were made with 35% silver to save copper for the war effort.

All U.S nickels, save for war nickels dated 1942-45, contain 75% copper and 25% nickel. As of 14 December 2013, U.S. nickels have a melt value of 4.46 cents.

Yes because after you save up alot of dimes it only takes ten unlike pennies so its not a complete waste of time.they can add up over time and who knows you might make bank

9.32 save %

With the passage of the Coinage Act of 1965, the composition of the dime changed from 90 percent silver and 10 percent copper to a clad "sandwich" of pure copper inner layer between two outer layers of cupronickel (75% copper, 25% nickel) alloy, giving a total composition of 91.67% Cu and 8.33% Ni. All nickels struck from 1866 to mid-1942 and since 1946 have been in 75% copper and 25% nickel. Those struck from mid-1942 to 1945 were made of silver, copper, and manganese to save nickel metal for the war effort. The current clad version of the quarter is two layers of cupronickel, 75% copper and 25% nickel, on a core of pure copper. The total composition of the coin is 8.33% nickel, with the remainder copper.

1984 isn't a special or significant year for the U.S. nickel. All nickels minted 1866-2015 (save for the silver war nickels of 1942-1945) have been made of the same mix of 75% copper and 25% nickel.

Save 70% on Your Total

According to Coinflation.com all nickels are worth 7 cents just for the metal value. Unless you have something with a collector value you could save all the nickels you get and have more money!!! Maybe they will go up in value over time.

The total after savings is 6.99
