alexgriva [62]

Answer:

The answer to your question is 43.7 g of chocolate

Step-by-step explanation:

Data

56% cocoa

mass of a chocolate bar = 78 g

Process

To solve this problem, use proportions and cross multiplication, consider the mass of the bar is 100%.

                          78 g of chocolate ------------------- 100%

                             x                          ------------------    56%

                                            x = (56 x 78) / 100

                                            x = 4368/100

                                            x = 43.68 g

-Round to the nearest tenth

             Mass of the chocolate = 43.7 g

How do I graph this?​
vfiekz [6]

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48

<h3>How to graph the inequalities?</h3>

The inequalities are given as:

x + 7y ≤ 49

6x + y ≤ 48

The domain and the range are:

x ≥ 0

y ≥ 0

This means that, we plot the inequalities x + 7y ≤ 49 and 6x + y ≤ 48 under the domain and the range x ≥ 0 and y ≥ 0

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48
