Priam has pennies and dimes in a cup holder in his car. the total value of the coins is $4.21. the number of dimes is three less than four times the number of pennies. how many pennies and how many dimes are in the cup?

There are 11 pennies and 41 dimes in the cup.

Step-by-step explanation:

Let the pennies be represented by = p

Let the dimes be represented by = d

The total value of the coins is $4.21. We get the first equation as:

    .......(1)

The number of dimes is three less than four times the number of pennies. We get the second equation as:

  ......(2)

Substituting the value of d from (2) in (1)

Solving this we get;

=>

=>

We get p = 11

And =

We get d = 41

Therefore, there are 11 pennies and 41 dimes in the cup.
