Let the number of dimes is d and number of quarters is q .

It is given that d=q and

Make a chart as follows.

    Number×Valuepercoin=Totalvalue
    Dimesd1010d
    Quartersq2525q

It is given that Julia has $1.80 more than Luis. Then

  25q=10(18+d)25d=180+10d15d=180d=12

As d=q so q=12 .

Therefore, each has 12 coins.
