Keith has p pennies, n nickels, and d dimes in his pocket. the total number of coins is 9. the expression 0.01p+0.05n+0.10d represents the value of the coins, which is equal to $0.44. he has one more dime than nickels. how many pennies does keith have? keith has pennies.

Keith has 4 pennies, 3 dimes and 2 nickels.

Step-by-step explanation:

Let the pennies be = p

Let the nickels be = n

Let the dimes be = d

Total coins Keith has = 9

So, 1st equation form :

    ....(1)

Keith has one more dime than nickels, means   .....(2)

Total value of these coins is $0.44

So, third equation forms:

  .....(3)

Substituting (2) in (1)

    .....(4)

Similarly substitution (2) in (3)

   ....(5)

Now multiplying (4) by 0.01 and subtracting by (5)

subtracting this from (5) we get

So, we get n = 2

p = 4

d = 3
