Answer 1

Answer:

24 cup cakes

Step-by-step explanation:

Karim uses. Total of 20 cup of batter to make x cupcakes and a cake. He uses 2/3 cups of batter for each cupcake and 4 cups of batter for the cake. How many cupcakes x can karim make if he uses all the batter

Let us represent:

Number of cup cakes = x

Number of cakes = y

x + y = 20 cups of batter

x + y = 20...... Equation 1

x = 20 - y

2/3 cups of batter for each cupcake and 4 cups of batter for the cake

Number of cups of batter for the cupcakes

= 20 - 4

= 16 cups of batter is used for the chop cakes

2/3 cups of batter for each cupcake

Hence:

2/3 cups of batter = 1 cup cakes

16 cups of batter = x

Cross Multiply

2/3 x x = 16

x = 16 ÷ 2/3

x = 16 × 3/2

x = 24 cup cakes
