b) 1071 dollars
c) Greatest--male architects, least--female nurses
Work Step by Step
Let $m$ and $f$ represent the amount male nurses make in a week and the amount female nurses make in a week, respectively.
a)
$m=89+f$
$.83m=f$
$m=89+.83m$
$.17m=89$
$.17m/.17 = 89/.17$
$m=523.53$
$m=89+f$
$523.53=89+f$
$434.53=f$
b)
Let $x$ and $y$ represent the amount male architects make in a week and the amount female architects make in a week, respectively.
$x=y+257$
$x=1.24y$
$y+257=1.24y$
$257=.24y$
$257/.24=.24y/.24$
$y=1070.83$
$x=y+257$
$x=1070.83+257$
$x=1327.83$
