Abdul bought a radio for $120. The same model is now on sale for $96. Express this decrease as a percentage of the original price. Show your work.
How would you do this problem?
[(120-96)/120]*100 = ??
Check my work.
$120 - 96 = $24.
$24 / 120 = 0.2 = 20%
Thank you. Could you please help me with these 2 other percent questions?
1. Margaret works at a local shoe store. She receives a 15% commission on every pair of shoes she sells. Margaret sold her friend a new pair of basketball shoes for $90. How much commission will Margaret receive from this sale? Show your work.
2. The shoe store marks up all of its shoes 40% from the wholesale price. If the store buys a pair of shoes for $56, find the retail price that a customer will pay for those shoes before tax. Show your work.
1. 0.15 * $90 = ??
2. 0.4 * $56 = X
$56 + X = Retail price
Thank you. Could you please tell me if these answers are right?
1. $13.50
2. $78.40
Right! :-)
To calculate the decrease as a percentage of the original price, you need to find the difference between the original price and the sale price, and then divide that difference by the original price.
1. Find the difference: $120 - $96 = $24. This represents the decrease in price.
2. Divide the difference by the original price: $24 ÷ $120 = 0.2.
To express this as a percentage, multiply the result by 100: 0.2 * 100 = 20%.
Therefore, the decrease in price is 20% of the original price.
