the admission charge in a water park is $ 1 by adult and $ 0.75 by child accompanying an adult . how much was there of child with an adult who paid in quite $ 3.25 to have access to the water park ?
n0 = 1.0
n1 = 0.75
n2 = 3.25
t0 = n0 * n2
t1 = t0 * 2.0
t2 = t1 - 0.25
t3 = t2 - 0.25
t4 = n0 + t3
answer = t4 - 4.0
