If we ask 500 individuals whether they have credit card and if we consider the probability of people having a credit card being normally distributed, then we assume that, considering 30% do not have a credit card, everyone who is within 1SD of the mean will have a credit card, while the remaining ~15% on either tail of the distribution do not.
You calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Example:
A computer software retailer used a markup rate of 40%. Find the selling price of a computer game that cost the retailer $25.
The markup is 40% of the $25 cost, so the markup is:
(0.40)(25) = 10
Then the selling price, being the cost plus markup, is:
25 + 10 = 35
The item sold for $35.
