Step-by-step explanation:
1. Real life problem: A store is having a sale where all items are 20% off. A customer wants to know how much they will save if they purchase an item that is originally priced at $25.
Solution: To find 80% of 25 (the discounted price of the item), we can multiply 25 by 0.80 (which is the decimal form of 80%).
80% of 25 = 0.80 x 25 = 20
Therefore, the customer will save $5 (the difference between the original price of $25 and the discounted price of $20).
2. Real life problem: A company wants to increase the price of one of their products by 60%. They need to know the new price of the product after the increase.
Solution: Let's call the original price of the product "x". We know that 180 is 60% of the original price, so we can write the equation:
180 = 0.60x
To solve for x, we can divide both sides of the equation by 0.60:
x = 180 ÷ 0.60
x = 300
Therefore, the original price of the product was $300. To find the new price after the 60% increase, we can multiply the original price by 1.60:
New price = $300 x 1.60 = $480
So the new price of the product after the 60% increase is $480.
