A pig
Find yourself a container and make a slit in the top big enough for the largest coin you wish to put in it and there you go, a piggy bank.

Yes, piggy banks are pottery models of pigs. They have a slot at the top to put money in, and may have a hole at the bottom to get it out. If they have no hole then you get the money out by smashing the pig. Since you can only do this once, this acts as an incentive for saving.The choice of the pig is because it can be moulded into a nice round shape.
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).

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.
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
In order to eliminate the decimal point, let us work with cents. So, let $ 4.50 = 450 cents. If the number of nickels is x, then the value of x nickels is 5x cents. Since the number of dimes is twice the number of nickels, then we can write the number of dimes as 2x, and the value of 2x dimes as 10(2x) or 20x cents. So we have: 5x + 20x = 450 25x = 450 divide by 25 to both sides x = 18 the number of nickels 2x = 2 x 18 2x = 36 the number of dimes Thus, Cameron has 18 nickels and 36 dimes. Check: 18 nickels = 18 x 5 cents = 90 cents or $ 0.90 36 dimes = 36 x 10 cents = 360 cents or $ 3.60 0.90 + 3.60 = 4.50? 4.50 = 4.50 True
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 ■
shake the piggy bank until all the coins get out.
The number of coins that can fit into an empty piggy bank depends on the size and capacity of the piggy bank, as well as the size and denomination of the coins. Generally, you could estimate by counting the volume of the coins and comparing it to the volume of the piggy bank.
