You have seven quarters and four pennies.
q + p = 11
p + 3 = q
(p + 3) + p = 11
2p + 3 = 11
2p = 8
p = 4
11 - 4 = 7
(1/5)*(1/4) = 1/20 the odds of a quarter falling out, multiplied by the odds of a quarter falling out after a single quarter has fallen out
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
1 brink = (¾+¼) brick = ¾ brick + ¼ brick If 1 brick balances ¾ brick + ¾ lb then: 1 brick = ¾ brick + ¼ brick = ¾ brick + ¾ lb → ¼ brick = ¾ lb (subtracting ¾ brick from both sides) → 1 brick = 3 lb (multiplying both sides by 4).
The first step in solving this problem is to build two equations. 0.25Q+0.10D=2.50 and Q+D=13 where Q=total number of quarters and D=total number of Dimes. Next we try to subtract one equation from the other to eliminate one variable. So we multiply 0.25Q+0.10D=2.50 by 4 to get 1Q+0.4D=10. Then we subtract Q+0.4D=10 from Q+D=13. This results in 0.6D=3. We divide both sides by 0.6 and end up with d=5. Therefore we have 5 dimes, which equals 50 cents. Therefore we have $2 in quarters or 8 quarters. 8 quarters is the answer.
two quarters and five penniesMoreThe puzzle is actually stated "How can you make 55 cents with two coins if one isn't a nickel?", which rules out the use of quarters and pennies.The answer is a half dollar and a nickel. The trick is that the question says only one can't be a nickel, it doesn't say they both can't be nickels.
If Keoki has 14 quarters and 8 dimes (for a total of 22 coins), she has $3.50 and $0.80 or $4.30 in coins. If Keoki has 15 quarters and 7 dimes (for a total of 22 coins), she has $3.75 and $0.70 or $4.45 in coins. If Keoki has 22 coins that are all dimes and quarters and their value in total is $4.35 as asked, there isn't a combination of coins that will permit her to have both 22 coins and $4.35 worth of coins.

I have exactly three coins in my pocket. If you can guess exactly how many coins I have, you can have them both.
(1/5)*(1/4) = 1/20 the odds of a quarter falling out, multiplied by the odds of a quarter falling out after a single quarter has fallen out
