<PRE><B>Question 76892</B>
Luis and Julia have the same number of coins. Luis has only dimes and Julia has only quarters.If Julia has $1.80 more than Luis does, how much does each have?
:
Let x be the number coins each has:
:
L amt + 1.80 = J amt
.10x + 1.80 = .25x
1.80 = .25x - .10x
1.80 = .15x
x = 1.80/.15
x = 12 coins each
:
:
Check solution
12 * .25 = 3.00
12 * .10 = 1.20
----------------
difference 1.80</PRE>
