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.

Let X equal the number of quarters X * 25 is the value of the quarters ((X+8) * 5) is the value of the nickels25X + 5X + 40 = 610 so 30X + 40 = 610 .subtract 40 from both sides , divide both sides by 30X = 19There are 19 quarters and 27 nickels in the piggy bank

117 nickles

He has 165 cents.

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).

shake the piggy bank until all the coins get out.

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.

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. :)

There is an extremely large amount of possibilities of money combinations that could be within a piggy bank. We must first note that some piggy banks differ in size, but the real problem is with the change itself. The piggy bank could be filled with all pennies, all quarters, 10 dimes and the rest quarters, and so on. The possibilities are limitless.

he tell piggy to count the littluns and find otu how many boys there are in total.

The origins of the term "piggy bank" come from the Old English word "pygg" which referred to an orange clay. This clay was used to make many things including dishes and jars to hold spare coins. The word pygg sounds much like the word pig, and probably was changed due to misunderstanding. I guess from there, the pygg jar for holding coins became a pig shaped jar, or piggy bank, for holding coins.

No. Coins are not a single metal but alloys. An element can contain only 1 species of molecule.

heres an idea COUNT

You could have: 8 nickels and 1 penny or 6 nickels and 11 pennies or 4 nickels and 21 pennies or 2 nickels and 31 pennies. The option of 0 nickels and 41 pennies is excluded by the necessity that the amount is made up of dimes, nickels and pennies; 0 nickels would mean the $1.21 was made up of dimes and pennies only.

6 pennies

8X5=40 and 5X1=5 so $0.45

They attack them at night because both Ralph and Piggy are in the head quarters sleeping, and at night is the time when they can't be as noticed as much, rather than day time.

Piggy banks are used for storing money, usually in the form of small bills or coins. They are named after an Old English pottery term, but are now commonly associated with the standard (animal) meaning of "pig."
