Answer:
0.40(80) --> markup of 40%
80 + 0.40(80) --> sale price after markup of 40%
0.25(80) --> discount of 25%
80 - 0.25(80) --> sale price after a discount of 25%
Step-by-step explanation:
If we want to know how much is a markup of 40% over the price of $80, we need to multiply 0.4 by 80, so:
0.40(80) represents a markup of 40%
Then, the final price with this markup can be calculated as the sum of the initial price and the markup, so:
80 + 0.40(80) represents the sale price after markup of 40%
On the other hand, if we want to make a discount of 25%, we first need to calculate the discount as 0.25 times the price, so:
0.25(80) represents the discount of 25%
Then, the final price after the discount will be the initial price less the amount that you will discount, so:
80 - 0.25(80) represents the sale price after a discount of 25%
So, the answers are:
0.40(80) --> markup of 40%
80 + 0.40(80) --> sale price after markup of 40%
0.25(80) --> discount of 25%
80 - 0.25(80) --> sale price after a discount of 25%
