(a) 35.8 + 10 need answer

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
