Question

Each of the 10 students in the baking club made 2 chocolate cakes for a fundraiser. They all used the same recipe, using C cups of flour in total. Write an expression that represents the amount of flour required for one cake.​

Answer 1

Answer:

$\frac{c}{20}$ cups

Step-by-step explanation:

Number of students in the baking club = 10

If each student made 2 cakes

then total cakes prepared by the students = 10 × 2 = 20

If total amount of flour used to prepare 20 cakes = c cups

and amount of flour used to prepare one cake = n cups

Then amount of flour used to prepare 20 cakes = 20n

Therefore, total amount of flour c = 2n

or n = $\frac{c}{20}$

Amount of flour used for one cake =  $\frac{c}{20}$ cups

Answer 2

An expression that represents the amount of flour required for one cake is C/20

From the question given, we have the following

Number of students in the baking club = 10

If each students made 2 chocolates each for the fundraiser, the total number of chocolate made will be 2 × 10 = 20chocolates cakes

If there use C cups of flour in total,  then

20 chocolate cakes will contain;

20 cakes  = C flour

To calculate for one cake

1 cake = x

Divide both expressions

20/1 = C/x

20x = C

x = C/20

Hence an expression that represents the amount of flour required for one cake is C/20.
