The baker needs to use 100/3 pounds of 90% chocolate to make the cake.

<h3>Equation </h3>

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the amount of 90% chocolate. Using equation:

100 * 70% + x * 90% = (x + 100) * 75%

100 * 0.7 + 0.9 * x = (x + 100) * 0.75

70 + 0.9x = 0.75x + 75

x = 100/3

The baker needs to use 100/3 pounds of 90% chocolate to make the cake.

Ginny’s favorite cookie recipe requires 1 1/2 cups of sugar to make 24 cookies. How much sugar does Ginny need to make 36 of the
Delicious77 [7]

Ginny needs 2\frac{1}{4} cups of sugar to make 36 cookies.

Step-by-step explanation:

Given,

Sugar cups required for 24 cookies = 1\frac{1}{2}=\frac{3}{2}\ cups

Ratio of sugar cups to cookies = \frac{3}{2}:24

Let,

x be the number of cups needed for 36 cookies.

Ratio of sugar cups to cookies = x:36\\

Using proportion;

Ratio of sugar cups to cookies :: Ratio of sugar cups to cookies

\frac{3}{2}:24::x:36

Product of mean = Product of extreme

24*x=\frac{3}{2}*36\\24x=54

Dividing both sides by 24

\frac{24x}{24}=\frac{54}{24}\\x=\frac{9}{4}\\x=2\frac{1}{4}

Ginny needs 2\frac{1}{4} cups of sugar to make 36 cookies.
