How many nickels and dimes are there if 344 coins total 28.75?

Assuming all the coins are either nickels or dimes: Let's call the number of nickels n and the number of dimes d.Since there are 344 coins, we can write the equation:n + d = 344There are 2,875 cents (28 dollars is 2,800 cents plus the 75 cents left over). Since nickles are five cents and dimes are 10 cents, we can write the equation:5n + 10d = 2,875We now have two equations:n + d = 3445n + 10d = 2,875These equations can be solved by substation or elimination. Here we'll solve them by elimination. We'll multiply the top equation by 10:10n + 10d = 3,4405n + 10d = 2,875Now subtract the bottom equation from the top one, which gives:5n = 565Divide both sides by 5:n = 113So there are 113 nickles. Plug that back into the equation n + d = 344 to find the number of dimes:113 + d = 344d = 231So there are 113 nickels and 231 dimes.
