What is the percentage of cacao in hot chocolate which is made of 480 grams of milk and 20 grams of cacao?

galina1969 [7]

Given that the hot chocolate is made of 480 grams of milk and 20 grams of cacao.

We need to determine the percentage of cacao in hot chocolate.

<u>The percentage of cacao:</u>

The total grams of hot chocolate can be determined by adding the total grams of milk and the total grams of cacao.

Total grams of hot chocolate = Grams of Milk + Grams of cacao

Total grams of hot chocolate = 480 + 20 = 500 grams.

Thus, the total grams of hot chocolate is 500 grams.

Now, we shall find the percentage of cacao.

The percentage of cacao is given by

$\frac{100}{500}\times 20$

Simplifying, the values, we get,

$\frac{2000}{500}=4\%$

Thus, the percentage of cacao is 4%

One number added to three times another number is 24. Five times the first number added to three times to other number is 36. Fi

Marrrta [24]

The numbers are 3 and 7

Step-by-step explanation:

Let the first number be x and the second number be y

Then according to given statement

One number added to three times another number is 24

x+3y=24 Eqn 1

Five times the first number added to three times to other number is 36

5x+3y=36 Eqn 2

Subtracting Equation 1 from equation 2

$5x+3y-(x+3y)=36-24\\5x+3y-x-3y=12\\4x=12$

Dividing both sides by 4

$\frac{4x}{4}=\frac{12}{4}\\x=3$

Putting x=3 in equation 1

$3+3y=24\\3y=24-3\\3y=21$

Dividing both sides by 3

$\frac{3y}{3} = \frac{21}{3}\\y=7$

Hence,

The numbers are 3 and 7

Suppose you have a coupon for 10% off and you use it to buy a CD which was already discounted 15%. Do you end up with a discount

Andrew [12]

No because the extra 10% is off the discounted price, not the original. image that the CD originally cost $10. 15% off of the CD would make the price $8.50. Another 10% off of $8.50 would make the price that you have to pay $7.65. 25% off of the original price of $10 would make the price $7.50. Sorry if its a bit confusing but I hope that helps!
