Answer

Lein earned 19,500 dollars while her husband earned 18,000 dollars.

Work Step by Step

Let $x =$ money Lien's husband's money (Lien's money) + (Her husband's money) $= 37500$ $(x + 1500) + (x) = 37500$ $2x + 1500 = 37500$ $2x = 36000$ $x = \frac{36000}{2}$ $x = 18,000$ dollars Therefore her husband earned 18,000 dollars. Let $L =$ money Lien earned $L = (x + 1500)$ $L = (18000 + 1500$ $L = 19,500$ dollars Therefore Lien earned $19,500 dollars.
