Answer:

  • 357 = 0.7×s
  • $510

Step-by-step explanation:

We are given the relation ...

  take-home pay = (7/10) × salary

Let s represent Alexandra's salary. Then the equation with the given take-home pay becomes ...

  357 = 0.7 × s

The solution is found by dividing both sides by 0.7.

  357/0.7 = s = 510

Alexandra's salary is $510 before taxes.
