Answer provided by our tutors
let
x = my paycheck
y = my coworkers paycheck
my paycheck is 15% less than your coworker's
x = y - 0.15*y = 0.85*y
two paychecks total $645
x + y = 645
by solving the equation
x = 0.85*y
x + y = 645
we find
x = $296.351
y = $348.649
my paycheck is $296.351, the coworkers paycheck is $348.649.
