Answer
The husband earns \$32500.
Work Step by Step
The husband's salary is an unknown quantity ($x$) and the woman's is 15% more ($1.15*x$). The total is \$69875:
$69875=x+1.15*x$
We solve for $x$:
$69875=2.15*x$
$x=69875/2.15=32500$
Thus the husband earns \$32500 and the woman earns 1.15*32500=\$37375.
