Problem 45758. Mo money, mo math 1! (★★★)

(adapted from Prob 9 Cody team)

You have a vector where the elements represent the number of $20 bills, $10 bills, $5 bills, $1 bills, quarters, dimes, nickels, and pennies that person has (in that order). Thus, there are 8 elements. What is the total amount of money?

Note for those unfamiliar with American coins: quarter = $0.25, dime = $0.10, nickel = $0.05, penny = $0.01.

Example:

Input  x = [1 0 0 0 0 3 0 0]
Output y = 20.30

since the wallet has one $20 bill and three dimes.
