Sofia is buying new skis. She finds that the average price of skis is $500 but the actual price could differ from the average as much as $250. Write and solve an absolute value inequality to describe this situation.
The equation that best represent the actual prices of the skis is, I x - 500 I ≥ 250 Solving the absolute value equation, x ≤ 750 and x ≥ 250 Thus, the prices of the skis ranges from 250 to 750.
