### Instruction: at a contest with 500 participants , 1 / 2 of the people are aged 28 to 32 . next year , the number of people aged 28 to 32 will increase by 1 / 8 . after this change , what percentage of the total 500 people will the 28 - to 32 - year - olds represent ? Let's program in Python in the response.### Response: n0 = 500.0
n1 = 1.0
n2 = 2.0
n3 = 28.0
n4 = 32.0
n5 = 28.0
n6 = 32.0
n7 = 1.0
n8 = 8.0
n9 = 500.0
n10 = 28.0
n11 = 32.0
t0 = n1 / n8
t1 = n0 / n2
t2 = t0 + n1
t3 = t2 * t1
t4 = t3 / n0
answer = t4 * 100.0
print(answer)
