Let X equal the number of quarters X * 25 is the value of the quarters ((X+8) * 5) is the value of the nickels
25X + 5X + 40 = 610 so 30X + 40 = 610 .
subtract 40 from both sides , divide both sides by 30
X = 19
There are 19 quarters and 27 nickels in the piggy bank

How many ways are there to choose eight coins from a piggy bank containing 100 identical pennies and 80 identical nickels?
C(8+1, 1)= c(9, 1) = [9!/1!(9-1)!] = [9!/1! 8!] = [9/1!] = 9.
How much money does Joe have to spend at the candy store if he has 3 quarters 1 dime and 2 nickels in his piggy bank?
Is this a trick question? Well, assuming that Joe breaks open his piggy bank, and Joe doesn't cut his finger on the little pieces and have to buy bandages, then he would have 95 cents to spend at the candy store. :)

A piggy bank has only nickels and dimes in it there are 14 coins worth 0.95. How many nickels and dimes are in the bank?
2 variables with 2 equations. A simultaneous equation problem. d+ n = 14 10d + 5n = 95 Multiply the first equation by -5 -5d + -5n = -70 10d + 5n = 95 add together 5d = 25 d = 5 ◄ plug that in the first equation to find n 5 + n = 14 n = 9 ◄ check 5 dimes plus 9 nickles is 50c+45c=95c ■

You piggy bank has all nickels and quarters. You count up the coins and find out that there are 64 coins and you have a total of 7.40. How many of each type of coin do you have?
The idea is to write two equations, one for the number of coins, one for the amount of money. Then solve the equations.Assuming "n" is the number of nickels, and "q" the number of quarters, the equations for the coins, of course, is quite simply: n + q = 64 And the equation for the money (I'll use cents; you can just as well use dollars if you prefer): 5n + 25q = 740 You can solve the first equation for "n", then replace that in the second equation.

If Charlie's piggy bank was filled with dimes and nickels and he took the money out and counted a total of 419 coins which were worth 36.05 how many nickels were in the piggy bank?
117 Alternative method: If all the coins were dimes he would have $41.90; He is $5.85 short of that figure Every 5c short represents 1 nickel replacing a dime 585/5 = 117 nickels (and 302 dimes).

When a piggy bank has 160 total coins valuing 10.50. Think about a system of equations that can be used to represent the number of nickels and dimes and then think through?
If n is the number of nickels and d the number of dimes, then the equations are:n + d = 160 (total number of coins) 5n + 10d = 1050 (total value). And I have thought through to the answer.
