let
x = the old hourly rate
y = the new hourly rate
We presume a calendar year consisting of exactly 52 weeks or 364 days
52*28*x + 52*200 + 12*120 = 49696
by solving we find:
x = $26 per hour

with the new hourly rate she is supposed to have a total annual income of $51,880 or:
52*28*x + 52*200 + 12*120 = 51880
by solving we find:
x = $27.5 per hour
click here to see the step by step solution of the equation:
$27.5 - $26 = $1.5
Desiree needs an hourly raise of $1.5.
