Consider a small ferry that can accommodate cars and buses. The toll for cars is $3, and the toll for buses is $10. Let X and Y denote the number of cars and buses, respectively, carried on a single trip. Suppose the joint distribution of X and Y is as given in the table below.

y
p(x,y) 0 1 2
x 0 0.025 0.015 0.010
1 0.050 0.030 0.020
2 0.085 0.075 0.050
3 0.150 0.090 0.060
4 0.100 0.060 0.040
5 0.050 0.030 0.060

Compute the expected revenue from a single trip. (Round your answer to two decimal places.)
