The ratio of Elaine's weekly salary to Carl's weekly salary is 3:2. If Elaine gets a 20% raise and Carl gets a $200 raise, the ratio of Elaine's salary to Carl's will drop to 6:5. Elaine's original weekly salary is
-----
Old salaries:
Let Elaine's be 3x ; then Carl's is 2x
-----
New salaries:
Elaine's is 1.2(3x) = 3.6x
Carl's is 2x+200
----------------------
Equation:
3.6x/(2x+200) = 6/5
18x = 12x+1200
6x = 1200
x = 200
----
Elaine's original salary is 3x = $600
