    Total number of quarters Aria has=6

    Total number of dimes Aria has=12

    Step-by-step explanation:

    The expression for the total value of money Aria has is;

    Quarters have a value of = $0.25

    Dimes have a value of = $0.10

    Total value = (value of quarters*number of quarters) + (value of dimes*number of dimes)

    where;

    Total value=$2.70

    Value of a quarter=$0.25

    number of quarters=x

    Value of a dime=0.10

    number of dimes=y, but y=2x

    replacing;

    2.70 = (0.25*x) + (0.1*2x)

    0.25 x+0.2 x=2.7

    0.45 x=2.7

    x=2.7/0.45

    x=6

    y=2 x=2*6=12

    Total number of quarters=6

    Total number of dimes=12
