Final answer:

To determine whether the student will owe more or less than $75 for the lost uniform, we can use mental math to find 75% of $105. The student will owe more than $75 for the lost uniform.

Step-by-step explanation:

To determine whether the student will owe more or less than $75 for the lost uniform, we need to find 75% of $105. We can use mental math to calculate this. 75% of a number is the same as three-quarters of that number. To find three-quarters of $105, we can divide $105 by 4 and then multiply the result by 3. $105 divided by 4 is $26.25, and $26.25 multiplied by 3 is $78.75. Therefore, the student will owe more than $75 for the lost uniform.
