B would equal logx (-2x^5/a)-2
A would equal -2x^3-b (The b is up there with the 3 as well. Like ^3-b)

There are 4 possible outcomes based on 2 types of wash (deluxe wash & other wash) and 2 vacuum uses (with vacuum and no vacuum). Since customers are equally likely to choose between these, we can run a uniform distribution from 1-4, where each represents one outcome. For example, 1 = deluxe+vacuum, 2=deluxe+no vacuum, 3=other wash+vacuum, 4=other wash+no vacuum. Then after running a large number of simulations (ex. 1000), count the number of the desired result (which is the number 2), and divide by the total number. This will give the probability.

Fourth grade average:
87 + 95 + 76 + 148 + 104 = 510 / 5 = 102
Seventh grade average:
183 + 187 + 204 + 215 + 196 = 985 / 5 = 197
