Answer:The percent change in unit price can be calculated using the formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100
In this case, the old value is 400 tissues per box and the new value is 350 tissues per box. Since there is no change in the price per box, we can focus on the change in the number of tissues.
Applying the formula, we have:
Percent Change = ((350 - 400) / 400) * 100
Simplifying the calculation, we get:
Percent Change = (-50 / 400) * 100
Percent Change = (-0.125) * 100
Percent Change = -12.5%
Therefore, the percent change in unit price when a box of tissues dropped from 400 to 350 tissues per box (with no change in the price per box) is -12.5%. This means that there was a decrease of 12.5% in the number of tissues per box.
