My question is: The cost of a slice of cake is three-fourths of the cost of a cup of milk tea. If the milk tea costs $2.40, how much do 2 slices of cake and 1 cup of milk tea cost? Your thoughts:
The cost of a slice of cake is $2.40 x 3 / 4 = $1.80. So, 2 slices of cake cost $1.80 x 2 = $3.60. Therefore, 2 slices of cake and 1 cup of milk tea cost $3.60 + $2.40 = $6. The final answer: 6.
