Not absolutely sure I understand the question, but should be 120
Answer:
Step-by-step explanation:
If the regular price of a T-shirt is 10 USD and the store sells off its wares at 80% of its regular price, then the price at which the store would still the aforementioned T-shirt would be 80% of its 10 USD price.
80% of $10 =
0.8 * 10 = $8
This means that the price at which the T-shirt will go for, due to the ongoing sales will be $8.
Also, being asked to find the 10% and 20% of $10 is just as simple
10% of $10 =
0.1 * 10 = $1
20% of $10 =
0.2 * 10 = $2
Therefore, the 10% and 20% of $10 is $1 and $2 respectively.
1.5 and 3/2. 1.5 because 1/2 is equal to 0.5. 3/2 because it can be converted into an improper fraction
The set is not closed
Example
-4 * -2 = 8
8 is not a negative integer
