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
