Step-by-step explanation:
To find the cost per pair of jeans, we need to divide the total cost by the number of pairs. In this case, you bought 3 pairs of jeans for $35.95 each and got a fourth pair for free. So, you paid a total of 3 * $35.95 = $107.85 for 3 pairs of jeans.
Since you got a fourth pair for free, you have a total of 4 pairs of jeans. So, your cost per pair of jeans is $107.85 / 4 = $26.96.
