Example Question #82 : Hspt Mathematics
Julie bought some groceries at the store where she works for $196.57. She got an employee discount of 15%. How much would the same groceries cost a non-employee?
Paying at a 15% discount is equvalent to paying 85% of the original price, so $196.57 is 85% of the original (non-employee) price, or, equivalently, 0.85 times that price. If 
A non-employee would pay $231.26 for the groceries.

Example Question #23 : How To Work With Percentages
For her birthday, Susan asks her mother to buy her a car. Susan’s mother agrees to give Susan 150 percent of whatever amount Susan can save up in six months. If Susan saves 
$900
$300
$700
$550
$750
$900
When Susan's mother agreed to match her savings plus fifty percent, she agreed to give Susan 
Before multiplying by the amount Susan saved, we must convert 
Now we multiply 
Susan's mother owes her $
Example Question #24 : How To Work With Percentages
If sales tax on a pair of jeans is 
$56
$58
$60
$66
$62
$58
Since the jeans are the only item being purchased, and they cost $
Note: In order to find the decimal form of a percent, we divide it by 
Find the tax:
Therefore the sales tax added to the original price is $
The final cost of the jeans is $
Example Question #851 : Numbers And Operations
At a pet store, there are 12 dogs and 8 cats. The following week, the number of dogs increases by 25%, while the number of cats decreases by 25%. What is the total number of animals at the store the following week?
Assume the store only sells dogs and cats.
If the population of dogs increases by 25%, then we first find 25% of 12 (which is 3) and add the 3 to 12. This gives us 15 dogs.
If the population of cats decreases by 25%, then we find 25% of 8 (which is 2), and subtract if from 8. This gives us 6.
Now that we know the final individual numbers of dogs and cats, we can add them to find the final answer.
