A store that buys and sells used video games buys a game at a cost of ​$19 and sells it at a selling price of ​$25. Find the markup. Then find the percent markup.

The markup is found by subtracting the cost from the selling price: $25 - $19 = $6.

The percent markup is found by dividing the markup by the cost, then multiplying by 100: ($6 / $19) * 100 ≈ 31.58%.
Therefore, the markup is $6 and the percent markup is approximately 31.58%.
