To find the ratio of the quantity of vanilla cupcakes to the total number of cupcakes, we first need to calculate the total number of cupcakes Amanda bakes.
Total cupcakes = Chocolate cupcakes + Vanilla cupcakes + Strawberry cupcakes Total cupcakes = 14 + 18 + 6 = 38
Now, we find the ratio of vanilla cupcakes (18) to the total number of cupcakes (38):
The ratio is 18:38.
So the correct response is 18:38.
