    Step-by-step explanation:If you have 84 coins total and your ratio of dimes to quarters is 3:4, that is 7 coins.

    12 times 7 is 84.

    At this ratio you will have 36 dimes and 48 quarters.

    36 dimes is $3.60 and the value of the quarters is $12.

    Added together they have a value of $15.60
