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.
