Arestaurant offers hamburgers with one, two, or three patties. let x represent the number of patties a randomly chosen customer orders on their hamburger. based on previous data, here's the probability distribution of x along with summary statistics:

x=# of patties 1 2 3
p(x) 0.40 0.50 0.10
mean: μx=1.7
standard deviation: σx≈0.67
the total price of each burger is set at $2 per patty. let t represent the total price a randomly chosen customer pays for their burger. find the mean of t
