Ответ:
Both are correct.
Step-by-step explanation:
Hi, both are correct.
Since the discount is 20%, to obtain the amount of the discount we have to multiply the price (p) by the sale percentage discount in decimal form (20/100=0.2)
So, it will be: 0.2p
If we subtract that amount to the original price, we obtain the sale price.
p-0.2 p ( Susan's method).
Since the discount is 20%, and the whole price is 100%,the sale price is equal to : 100%-20%= 80%
We also can calculate the sale price by multiplying the price (p) by the sale price percentage in decimal form (80/100=0.8).
p0.8 (Michael's method)
