there are 8 stores in town that had a total of 22 visitors on a particular day . however , only 12 people went shopping that day ; some people visited more than one store . if 8 people visited exactly two stores each , and everyone visited at least one store , what is the largest number of stores anyone could have visited ?
n0 = 8.0
n1 = 22.0
n2 = 12.0
n3 = 8.0
t0 = n0 * 2.0
t1 = n2 - n0
t2 = n1 - t0
t3 = t1 - 1.0
answer = t2 - t3
print(answer)
