Answer:

100. his save

Step-by-step explanation:

because the 20% of 500 is 100 And total his bought is400

Answer:

1. The percentage given a base of 40 and a rate of 20% is 8.

To solve for the percentage, we can use the formula:

Percentage = (Rate / Base) x 100

Plugging in the values given, we get:

Percentage = (20 / 40) x 100

Percentage = 0.5 x 100

Percentage = 50%

However, the question asks for the percentage, not the answer to the formula. Therefore, the answer is 8%.

2. To find out what is 64% of 50, we can use the formula:

Part = (Percentage / 100) x Whole

Plugging in the values given, we get:

Part = (64 / 100) x 50

Part = 0.64 x 50

Part = 32

Therefore, 64% of 50 is 32.

3. Given a base of 300 and a rate of 9%, we can solve for the percentage using the same formula as in question #1:

Percentage = (Rate / Base) x 100

Plugging in the values given, we get:

Percentage = (9 / 300) x 100

Percentage = 0.03 x 100

Percentage = 3%

Therefore, the percentage given a base of 300 and a rate of 9% is 3%.

4. If Mr. Dela Cruz bought a bag with an original price of 500 pesos and got a discount of 20%, he saved:

Discounted Price = Original Price - (Original Price x Discount Rate)

Discounted Price = 500 - (500 x 0.20)

Discounted Price = 500 - 100

Discounted Price = 400

The discounted price of the bag is now only 400 pesos. Therefore, Mr. Dela Cruz saved 100 pesos.

Therefore, Mr. Dela Cruz saved 100 pesos.
