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 for one cake. Use C as your variable.

Answer 1

C / 20

Explanation:

Number of students in the baking club = 10

Each student made 2 chocolate cakes

Total cakes = number of students × number of cakes per student

= 10 × 2

= 20

Total cups of flour used by 10 students = C cups

Amount of flour for one cake = Total cups of flour / Total cakes

= C / 20

The expression that represents the amount of flour for one cake = C / 20
