Vince is interviewing for a job. He wants his take-home pay to be at least $42000. What is the least salary he can earn if he pays 25 income tax

Answer: $56,000

Step-by-step explanation:

If he pays 25% income tax, he is retaining 75% of his income.

So, his total income (let's call this x) times 75% (.75) should be $42,000.

Or, in equation form:

.75x = 42000

Solve this equation and you should get $56,000.
