b-1)How many of the guests were at least 26 but less than 30 years old = 3
b-2)What percent of the guests were at least 22 but less than 26 years old= 0.01*100= 1%
b-3)What percent of the guests were younger than 34 years old = (70/100)*100= 70%
b-4)What percent were 34 years or older= (30/100)*100= 30%
