All the merchandise in the store is reduced by 30%. If a microwave was discounted by 48 dollars what would be the discount on a product double the price of the microwave?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Given that the discount on the microwave is 48 with a 30% reduction:
\( 48 = \text{{Original Price of Microwave}} \times 0.30
Solving for the Original Price of Microwave:
Step 2: Calculate the price of a product double the original price:
Step 3: Calculate the 30% discount on this new product price:
Therefore, the discount on a product double the price of the microwave under the same conditions is .
96 $
Calculate 30 over 100 as a percentage:
Great question! While the final answer happens to be $96, doubling the discount is wrong reasoning. You got lucky this time because when you double the price, the discount also doubles. But this won't work for different percentage changes!
Use the formula: Original Price = Discount Amount ÷ Discount Rate. Here: dollars. Think of it as working backwards from the discount.
Same process! Find the original price (480), then calculate 30% of that: dollars discount.
Because 30% means 30 out of 100, which equals . Multiplying by 0.30 is the same as finding 30% of a number.
Multiply your original price by the discount rate: . If you get the given discount amount ($48), you're right!
