Ineed to make $500 per week after tax in order to pay all my bills. the income tax is 20%. what is the smallest pre-tax weekly salary i can earn and still be able to pay my bills after i pay my income tax?

let x be the amount I need to earn pre-tax.

Set up an inequality:

x - 0.2x >= 500

0.8x >=500

x>= 500/0.8
