Today most Americans live in cities or suburbs, but from colonial times into the early twentieth century a majority of Americans lived in the countryside and worked on farms. Only two percent of Americans live on farms or ranches today, but in 1790 ninety percent of the population did. What caused this shift?
The movement of populations from rural to urban areas is called urbanization. Urbanization in the United States increased gradually in the early 1800s and then accelerated in the years after the Civil War. By 1890, twenty-eight percent of Americans lived in urban areas, and by 1920 more Americans lived in towns and cities than in rural areas.^1
75% means 75/100, which is 3/4 simplified. You can set up the equation 36=3/4*x, with x being the number he attempted. Divide by 3 and multiply by 4 on both sides, and you get 48=x. Thus, Tim attempted 48 free throws.
