Practice one SAT question at a time

Questions come from the Bluebook question bank.

A student council group is selling school posters for a fundraiser. They use the function px=5x-220 to determine their profit px, in dollars, for selling x school posters. In order to earn a profit of $900, how many school posters must they sell?

Use the exact value the question expects unless it says to round.
