( im not really sure) i think it would be a, sorry if im wrong!
Each drink costs $1.75.
Total cost is represented by c.
Number of drinks is represented by d.
c=1.75d
Since there are 60 seconds in a minute multiply 8 by 60
The rate is 480 feet per minute.
I would say A but I’m not 100% sure.
A = P(1 + r)^t
A = 400(1 + .04)^1
A = $416
