Luis & Julia have the same number of coins. Luis has only dimes & Julia has only quarters. If Julia has $1.80 more than Luis does, how many coins does each have?
--------------------
Luis has "x" dimes that are worth 10x cents
Julia has "x" quarters that are worth 25x cents
--------
INEQUALIty:
Julia value - 180 cents = Luis value
25x-180 = 10x
15x=180
x=12 (number of dimes Luis has)
x=12 (number of quarters Julia has)
-----------
