conversations.value: Can you explain how to solve this math problem: 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?

conversations.value: 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.
