Example Question #11 : Sale Prices
A car dealer purchased a used truck, marked it up to make a 30% profit, then sold it at a 30% discount from the sticker price.
Quantity A: The amount that the dealer paid for the truck
Quantity B: The amount for which the dealer sold the truck
Quantity A is greater
The relationship cannot be determined from the information given
The two quantities are equal
Quantity B is greater
Quantity A is greater
Since no price is given, you can pick $100 as the starting point for the value of the truck. $100 marked up 30% is $130, and the 30% discount brings it to $91.
Example Question #81 : Percentage
A retail chain wishes to make at least a 
None of the answers are correct.
Let's begin by finding the absolute amount necessary for a 27% profit. Following that, we will adjust for the needs of having a whole number price. If the sale price is S, we can set up the following equation:
(S – 23)/23 = 0.27
S – 23 = 6.21
S = 29.21
The product must, however, be sold for at least $30 because it has to be an integer value.
Example Question #82 : Percentage
A car dealer sold two trucks for 
Quantity A: The dealer's net gain
Quantity B: The dealer's net loss
Quantity B is greater.
Quantity A is greater.
The relationship cannot be determined from the information given.
The two quantities are equal.
Quantity B is greater.
For the profitable truck, the dealer bought it for 
For the unprofitable truck, the dealer bought it for 
Thus, the dealer's net profit is $8,000, and the dealer's net loss is $10,000.
His loss is greater than his profit, so Quantity B is larger.
Example Question #12 : Sale Prices
The price of a laptop is reduced by 
Cannot be determined
To solve this problem, imagine that the original price of the laptop is $100. After the first 20% discount, the price of the laptop becomes $80. With the additional 10% reduction, we discount from $80, not $100. 10% of 80 is 8 so we must deduct $8 from $80. This gives $72 as the final price of the laptop after both reductions. Since we started at $100, the total discount is 28%.
