D because they all increase by the same number (+1)
I think that the right answer is $5 because if he want 4 toppings, that would be 0.75+0.75+0.75+0.75 which is 3 and ten you do 2+3=$5
Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.
First one hope this helps!
