Daniella is interviewing for a job. She wants her take-home pay to be at least $51,000. What is the least salary she can earn if she pays 15% income tax?

Let Daniella gross pay = P, then we have:

P - [15%*P) = $51,000

P - 0.15P =$51,000

0.85P =$51,000 divide both sides by 0.85

P = $51,000 / 0.85

P = $60,000 - The least salary that Daniella must earn.
