Easy
If your bill is $20 and you leave a 15% tip, how much tip do you leave?
$2.5
$4
$5
$3
15% of $20 is calculated by multiplying 20 by 0.15, which equals $3. This is the correct tip amount.
What is 20% of 100?
10
15
25
20
20% of 100 is found by multiplying 100 by 0.20, which gives 20. This demonstrates the basic calculation of a percentage.
A store advertises a 25% discount on a $40 item. What is the price after discount?
$30
$32
$25
$35
A 25% discount on $40 is calculated by finding 25% of 40, which is $10, and subtracting it from $40 to get $30. This is the sale price after discount.
If a $60 item has a 5% sales tax, what is the total cost?
$62
$60
$63
$66
A 5% tax on $60 is calculated as 60 multiplied by 0.05, which equals $3. Adding this to the original $60 results in a total of $63.
What is the discount amount when a 50% discount is applied to a $80 item?
$50
$20
$40
$30
A 50% discount on $80 is calculated by multiplying 80 by 0.50, which equals $40. This is the amount that is deducted from the original price.
Medium
A jacket is marked at $120, but is on sale for 30% off. What is the sale price?
$80
$90
$84
$96
A 30% discount on $120 is $36, so subtracting $36 from $120 gives a sale price of $84. This problem reinforces the concept of applying percentage discounts.
If you add a 10% tax to a $75 purchase, what is the final price?
$80
$90
$85
$82.50
A 10% tax on $75 is calculated as 75 multiplied by 0.10, which is $7.50. Adding this tax to the original amount results in a total of $82.50.
Calculate 15% of 200.
25

35
30
Multiplying 200 by 0.15 yields 30, which is the answer. This question reinforces the basic computation needed for percentage problems.
A restaurant bill is $56. If you leave a 20% tip, how much extra will you pay?
$12
$11.20
$13
$10
A 20% tip on a $56 bill is computed as 56 multiplied by 0.20, which equals $11.20. This amount is added to the bill as the tip.
A laptop is on sale for 25% off its $800 price. What is the discount amount?
$250
$150
$200
$100
A 25% discount on an $800 laptop is found by multiplying 800 by 0.25, resulting in $200. This is the amount that will be deducted from the original price.
A store increases the price of a product by 8% during a seasonal change. If the original price was $50, what is the new price?
$56
$54
$55
$52
An 8% increase on a $50 item is calculated as 50 multiplied by 0.08, which is $4. Adding this to the original price gives a new price of $54.
If a product that originally costs $150 is discounted by 10% and then an additional 5% off is applied on the discounted price, what is the final price?
$135.00
$128.25
$121.50
$129.00
First, a 10% discount on $150 reduces the price by $15 to $135. Then, a further 5% reduction on $135 subtracts an additional $6.75, resulting in a final price of $128.25.
An item's price increases from $40 to $48. What is the percentage increase?
15%
30%
20%
25%
The price increase from $40 to $48 is $8. Dividing this increase by the original price ($40) and multiplying by 100 gives a 20% increase.
After applying a 12% sales tax to a $100 purchase, if a coupon deducts $10 from the total, what is the final amount you pay?
$102
$112
$100
$110
A 12% tax on $100 adds $12, totaling $112. Subtracting the $10 coupon from $112 results in a final payment of $102.
A meal costs $90 before tax. If the tax rate is 7% and you wish to leave a tip of 15% on the pre-tax amount, what is the total amount spent?
$110.00
$107.70
$108.00
$109.80
A 7% tax on $90 adds $6.30 and a 15% tip adds $13.50, so the total amount is calculated as $90 + $6.30 + $13.50 = $109.80. This reinforces the importance of applying multiple percentages correctly.
Hard
A store offers a 40% discount on an item, and then adds a 5% sales tax on the discounted price. If the original price was $200, what is the final price?
$130
$120
$126
$126.50
A 40% discount on $200 reduces the price by $80, making it $120. A 5% tax on $120 adds $6, bringing the final price to $126. The order of applying discount then tax is key.
If a product's price increases by 20% and later decreases by 20%, is the final price equal to the original? If not, what is it as a percentage of the original price?
96% of original
104% of original
120% of original
100% of original
Increasing by 20% multiplies the price by 1.20 and decreasing by 20% thereafter multiplies it by 0.80. The overall effect is 1.20 x 0.80 = 0.96, or 96% of the original price.
A restaurant bill shows a subtotal of $80. After adding 8% tax and then a 15% tip on the subtotal, what is the correct total amount you would pay?
$98.40
$96.80
$100.00
$102.40
An 8% tax on $80 adds $6.40, and a 15% tip on $80 adds $12. The sum of $80, $6.40, and $12 gives a total of $98.40.
An item's price is reduced by 30% and then is subject to a 10% sales tax on the reduced price. If the item originally cost $250, what is the final price?
$192.50
$200.00
$175.00
$190.00
A 30% discount on $250 subtracts $75, reducing the price to $175. A 10% tax on $175 is $17.50, so the final price becomes $175 + $17.50 = $192.50.
A store advertises a 'Buy one, get one at 50% off' deal on a $120 item. What is the effective percent discount on the combined purchase of two items?
25%
15%
20%
30%
Normally, two items cost $240. With the deal, you pay $120 for the first item and $60 for the second, totaling $180. This results in a discount of $60, which is 25% of $240.
