Can anyone answer

Answer 1

Answer:

180 grams

Step-by-step explanation:

grams of dark chocolate= 200 % cocoa =60%

Grams of milk chocolate: 200 % cocoa=30%

Amount of cocoa in mixture:

(proportion of milk chocolate+ dark chocolate)

(30% of 200)+60% of 200)

(0.3* 200)+(0.6 *200)

60+120

=180 grams

Answer 2

Answer:

$45\%$

Step-by-step explanation:

The 200g mixture of dark chocolate is 60% cocoa, meaning there are $200\cdot 0.6=120$ grams of cocoa in this mixture.

The 200g mixture of milk chocolate is 30% cocoa, meaning there are $200\cdot 0.3=60$ grams of cocoa in this mixture.

When mixed together there are a total of 200+200=400 grams of content. Of these 400 grams, 120+60=180 of them are cocoa.

Thus, the concentration of cocoa in the resulting mixture is:

$\frac{180}{400}=\fbox{ 45\% }$
