Coins

first, what coins are available :
p = Penny
north = Nickel
vitamin d = Dime

Reading: Coins

q = quarter
heat content = Half dollar

Some combination of these coins must equal $ 1.00, consequently

.01p + .05n + .10d + .25q + .5h = $ 1.00
p + n + d + q + planck’s constant = 19

Questions we should consider :

  1. Can we achieve a solution with only one type of coin ? No .
  2. 100 pennies = $1

  3. 20 nickels = $1

  4. 10 dimes = $1

  5. 4 quarters = $1

  6. 2 half dollars = $1

  7.  

What happens if we use pennies ?

  1. Pennies must be used in multiples of 5, otherwise we can not reach a whole issue
  2. Since we can not use 20 pennies, we can merely use 5, 10, or pennies

If we use 5 pennies

  1. .05n + .10d + .25q + .5h = $0.95

  2. n + d + q + h = 14

nowadays consider nickels

  1. 14 nickels only equals $ 0.70, so we need to reduce the number of nickels
  2. If we use 12 nickels
  3. .10d + .25q + .5h = $0.35

  4. d + q + h = 2

now consider the other coins

  1. It seems clear up from this steer that we will need 1 dime bag and 1 quarter
  2. .01(5) + .05(12) + .10(1) + .25(1)= $1.00

Are there other combinations that can be made using 5 pennies ?

Let ’ s consider nickels :

  1. 18 nickels = $ 0.90
  2. We can only use 1 mint and it must equal $ 010, so in this font it must be 1 dime bag
  3. .05(18) + .10(1) = $1.00

  4.  

now let ’ s look at dimes :

  1. 9 dimes = $ 0.90
  2. We must use 10 more coins and they can ’ t sum to more than $ 0.10
  3. 1 nickel and 5 pennies sums to $ 0.10, but only requires 6 coins
  4. consequently, the only option is to use 10 pennies
  5. .01(10) + .10(9) = $1.00

nowadays let ’ s look at quarters :

  1. 3 quarters = $ 0.75
  2. We must use 16 more coins and they can ’ metric ton sum to more than $ 0.25
  3. 2 dimes and 1 nickel sums to $ 0.25, but only requires 3 coins
  4. 15 pennies and 1 dime has the adjust total and correct number of coins
  5. .01(15) + .10(1) + .25(3)= $1.00

  6.  

  7. 1 quarter = $ 0.25
  8. We must use 18 more coins and they can ’ t sum to more than $ 0.85
  9. 2 dimes and 1 nickel sums to $ 0.25, but lone requires 3 coins
  10. 15 pennies and 1 dime has the right sum and discipline number of coins
  11. .01(10) + .05(1) + .10(7) + .25(1)= $1.00

now let ’ s count at half dollars :

  1. 1 half dollar = $ 0.50
  2. We must use 18 more coins and they can ’ deoxythymidine monophosphate sum to more than $ 0.50
  3. 15 pennies and 1 dime bag sums to $ 0.25, but we can ’ triiodothyronine reach $ 1 with merely 2 coins
  4. 10 pennies, 1 dime bag, and 1 nickel sums to $ 0.25, but does not use enough coins
  5. .01(15) + .10(1) + .25(3)= $1.00

  6.  

Does adding the equations help ?
