two coins tossed can wind up h h ht t h t t 1/4 chance of h h
Not sure
(3m+5)(n-2) = 3mn + 5n - 6m -10
a = adults revenue = $ 17a
c = children = 531-a revenue = $ 12(531-a) revenues summed = $ 8167
17a + 12(531-a) = 8167 solve for 'a' the # adult tix then child tix= 531-a

Assuming it hits within the rectangle
prob = (area rectangle - area semicircle)/ area rectangle
(15x20 - 1/2 pi 10^2 ) / (15x20) = ............
arccos 4000 / 4005 = 2.863o
(2.863 x 2)/360 x 4000 pi = ~~ 200 miles
12 d / 5c = 2.4 dollars/coin
