Answer:
$720
Step-by-step explanation:
$1,200 divided by 2 (600) equals how many vanilla cupcakes there were.
40 people times 24 cupcakes each person (960) equals how many total cupcakes there were.
The total amount of cupcakes minus the amount of vanilla cupcakes equals the amount of chocolate cupcakes (960-600=360).
360 chocolate cupcakes times the amount each cupcake was sold for equals the amount of money raised from the chocolate cupcakes (360x2=720).
